Sub-agents are opted in only via an explicit `subagent.verify` section — `delegate_tasks` never enables it implicitly, so N children cannot multiply verify cost. diff --git a/cmd/odek/http_request_tool.go b/cmd/odek/http_request_tool.go index 01259d51..7386ad7a 100644 --- a/cmd/odek/http_request_tool.go +++ b/cmd/odek/http_request_tool.go @@ -7,6 +7,7 @@ import ( "io" "net/http" "net/url" + "sort" "strings" "time" @@ -91,6 +92,26 @@ func (t *httpRequestTool) checkURL(target string) error { return t.dangerousConfig.CheckOperation(danger.ToolOperation{Name: t.Name(), Resource: target, Risk: danger.ClassifyURL(target)}, nil) } +// toolsHTTPRequestResource renders the request for an approval prompt: +// method, URL and header names.

The `http_request` tool follows the same line (`danger.HTTPRequestClass`): a mutating method (anything but GET, HEAD, OPTIONS, TRACE; an unknown spelling fails closed) or a credential-bearing header (`Authorization`, `Cookie`, `X-Api-Key`, `Private-Token`, any name containing auth/token/secret/session/key-like fragments) is `network_upload`, checked by the tool itself and shown as such on the batch card; the approval text names the method, URL and header names but never header values. Unlike `persistence`, the session-trust shortcut stays available (friction rules still apply), and scheduled runs deny it unless `schedules.dangerous` allows it. **The `unread_exec` class (unread-script gate).** Executing a repo-supplied script — directly (`./env.sh`), via an interpreter (`bash env.sh`, `python tool.py`), or by sourcing it (`source env.sh`) — or by feeding it to an interpreter indirectly (`cat env.sh | bash`, `bash <(cat env.sh)`, `eval "$(cat env.sh)"`, `find -exec ./env.sh`, program-file options such as `awk -f`, `sed -f`, `make -f`, `gdb -x`, `vim -S`, `emacs --script`) — whose contents have not been read **in this session** gates as `unread_exec`. A read ledger (`danger.RecordRead`/`WasRead`) is populated by full-file `read_file` calls (a partial offset/limit window over a longer file does not count — the payload can ride below the fold), by `write_file` with the exact authored content, and by a successful plain `cat file` whose captured stdout matches the entire unchanged host file. `head`, `tail`, pagers, transformed output, shell syntax, container viewers, and partial patches do not grant execution-read trust. Native byte caps and the loop’s later output clipping/redaction invalidate delivery receipts; a tool read alone is not a delivered read. A **failed** read never licenses execution — the observed failure mode of a capable model whose `cat` errored on a path typo and fell back to running the file stays gated. The gate intercepts approval even when `code_execution` was set to `allow` or its class trusted (the entire point is per-script review), is never session-trust-shortcuttable (`danger.TrustShortcutAllowed`, all three approvers), and participates in configuration like a class: `"unread_exec": "deny"` blocks unread-script execution outright; `"unread_exec": "allow"` permits it only when the underlying class is also allowed — both must allow. **Fingerprinted licenses (TOCTOU).** The ledger binds each read to the file state at display time (size + mtime + SHA-256 of the exact displayed bytes, for files up to 1 MiB; larger files never receive a stat-only license): a file mutated after its read — via another tool, a lifecycle hook, or a background process — loses its license and the gate re-fires until the mutated content is re-read (re-reading renews the fingerprint, because now the model has seen THAT). **Pre-execution content audit.** When the gate prompts, the approval description carries content evidence from the local injection scanner over the target's leading 256 KiB, including a best-effort single-layer base64 (standard and URL-safe alphabets)/hex decode of embedded blobs — the human decides with the bytes, not just a path. The audit is read-only and never populates the ledger (the auditor is not the model). **Session-keyed ledgers.** Long-lived surfaces (`serve`, `telegram`, `schedule`) stamp `danger.WithLedgerKey` on the run context; file/shell tools record and gate against that key, so a read in session A cannot license execution in session B. An interpreter whose program operand only exists at run time (`bash "$(pwd)/x.sh"`, `bash "$DIR/x.sh"` with an unknown `DIR`, `xargs -I{} bash {}`) names a file no licence can be checked against, so it classifies `unknown` rather than running an unreviewed script behind a plain `code_execution` prompt; a process substitution (`bash <(cat x.sh)`) is a stream whose body is gated on its own. Ledgers are bounded (4096 paths per session, oldest evicted first; 1024 sessions, least recently used evicted first) and dropped with `danger.ForgetReadLedger` when a serve session is deleted, a Telegram chat is reset, or a scheduled run ends; eviction only removes a license, so the script gates again until re-read. A rewrite of the script inside the same command (`… > x.sh && bash x.sh`, `sed -i … x.sh; ./x.sh`) revokes its licence, a decoded or decompressed stream piped into an interpreter (`base64 -d … | sh`, `zcat … | python3`) classifies `unknown` because nobody has read its bytes, and fingerprinting never opens a non-regular file, so a FIFO cannot stall the gate. `Classify()` / `ClassifyScriptGate()` without a context still use the process-global default ledger (CLI-shaped tests and the classifier itself). @@ -214,7 +214,7 @@ When a classification is set to `prompt`, an approver pauses the agent until the - **Test binaries fail closed.** Inside a `go test` binary, the TTYApprover never opens the real controlling terminal — a test process without an explicit fixture TTY path (`/dev/tty` or empty) is denied outright instead of silently approving, covering both the test-binary case and the zero-value approver whose legacy path was fail-open. Approvers with an explicit fixture TTYPath are unaffected. - **Prompt text is escaped.** Approval prompts (terminal, WebSocket UI frames, Telegram, the batch card, project MCP and sandbox prompts) and the error strings of denied operations print model- or repo-supplied text through `danger.SanitizeForDisplay` / `SanitizeInline`: control characters, ANSI/OSC escapes, carriage returns, bidi controls and invisible format characters become visible escapes (`\x1b`, `\u202e`), multi-line values are indented so they cannot forge a prompt field, and an over-long value keeps its head and last kilobyte around an explicit `…[N more bytes]` marker. The terminal transcript applies the same escaping to model- and tool-sourced text (tool calls and result summaries, streamed reasoning and answers, thinking, final answers, narration, errors, memory and skill notices): newlines and tabs are kept where the renderer prints multi-line text, emoji joiners are kept inside emoji sequences, tag characters are kept only inside the RGI subdivision flags (England, Scotland, Wales: U+1F3F4, the code spelled in tags, the cancel tag) — a tag run after a black flag is held, at most five tags, until the cancel tag decides, and any other run is escaped whole, as are tags anywhere else — and a multibyte character or two-byte C1 control split across stream fragments is held back until it is complete, so an escape sequence in a fetched page cannot rewrite what the operator reads. -**Batch approval card.** `classifyToolCall` (in the loop) classifies each individual `shell` command, each `patch`/`write_file` target, and the `browser` tool (action + URL → `network_egress`); MCP tools (detected by the `__` naming convention) classify as `unknown`.

Promoted descriptions are flattened to one line, capped at 200 characters, and every catalog field passes through `danger.SanitizeInline`, so control, bidi and invisible characters arrive escaped. -**Promotion is operator-only.** `odek skill promote ` clears `NeedsReview` so a reviewed skill can load again; when the skill carries `Untrusted=true` or a non-empty `Sources` list, promotion is refused unless the operator passes `--force`. `odek skill import` stamps every imported skill with `Untrusted=true` and the fetch URI as its only `Sources` entry (remote frontmatter provenance is discarded), so an imported skill always requires `--force`. The promote command is a CLI/REST surface only — it is never exposed as an agent tool, so a prompt-injected agent cannot clear the gate on its own. +**Promotion is operator-only.** `odek skill promote ` clears `NeedsReview` so a reviewed skill can load again; when the skill carries `Untrusted=true` or a non-empty `Sources` list, promotion is refused unless the operator passes `--force`. `odek skill import` stamps every imported skill with `Untrusted=true` and the fetch URI as its only `Sources` entry (remote frontmatter provenance is discarded), so an imported skill always requires `--force`. A skill promoted from the project-local `./.odek/skills/` directory always counts as sourced from `"project"` — the promote command applies the same pin as the scanner, so a project `SKILL.md` that omits provenance frontmatter also requires `--force` (CLI) or `force: true` (REST), and `"project"` stays in the promoted file's `Sources` as the audit trail. The promote command is a CLI/REST surface only — it is never exposed as an agent tool, so a prompt-injected agent cannot clear the gate on its own. Skill writes (e.g. `odek skill import`) go through `WriteSkill`, which runs `internal/redact` over every SKILL.md write — detected credentials are replaced with `[REDACTED]` and the skill pinned to `NeedsReview`. The loader also refuses symlinked skill directories and symlinked `SKILL.md` files. diff --git a/docs/WEBUI.md b/docs/WEBUI.md index 46f5acb8..d4b9fe71 100644 --- a/docs/WEBUI.md +++ b/docs/WEBUI.md @@ -643,7 +643,8 @@ withheld (they may carry credentials). ### `POST /api/skills/promote` `{name, force?}` — the REST face of `odek skill promote`: clears -NeedsReview so a skill can auto-load.

Versioned names (`python3.12`, `lua5.4`) match the same rule. Direct eval/script-file forms of those interpreters (`python3.12 -c '…'`, `python3.12 script.py`, `lua -e '…'`, `lua pwn.lua`, `osascript -e '…'`, `ipython -c '…'`, `deno eval '…'`, `deno run script.ts`) are also `code_execution` — they are not auto-allowed just because they were recognised as stdin interpreters. `python3.12 --version` / `deno --version` stay `safe`. - `echo "/" | xargs rm -rf`, `echo / | parallel rm -rf`, `xargs rm -rf <<` retains the nested command’s effects.

Reads (`gh pr view`/`list`/`diff`, `gh issue list`, `gh repo view`/`clone`, `gh run view`, `gh search …`, `gh api` with a GET/HEAD (or no) method and no body flags, `gh auth status`) stay `network_egress`. Remote mutation (`pr merge`/`create`, `issue edit`, `release create`, `workflow run`, `secret set`, `gh api` with `-X POST`/`PUT`/`PATCH` or a body flag, a GraphQL `mutation`) is `system_write` (prompt). Irreversible deletion (`repo delete`, `release delete`, `gh api -X DELETE`, …) is `destructive`. `gh auth token` and `gh auth status --show-token` put a bearer token in the output, and login/logout/refresh change stored credentials, so they are `system_write`. Verbs that run a local program or shell alias (`extension install`/`exec`, `alias set` with a `!` expansion or `--shell`, `codespace ssh`/`cp`/`ports forward`, `copilot`, `config set editor`/`pager`/`browser`, git flags after `--` on `repo clone`) are `code_execution`. `run download`/`release download`/`repo clone` destinations (`-D`, `-O`, the clone directory, or the working directory) go through the write-target rules, so a download into `~/.ssh` or `.git/hooks` escalates. Only repo/host options (`-R`, `--repo`, `--hostname`, in any spelling) may precede the verb; an unrecognised command or verb, or any other option before the verb, is `unknown` (deny). `gh help`, `--help`, `--version` and `completion` stay `safe`. - `odek …` — any shell stage whose program basename is `odek` is `system_write`, so human-gated trust mutations (`odek memory promote`, `odek skill promote --force`, …) always require explicit operator approval and an injected agent cannot flip its own taint gates from inside a session. - `echo x >> ~/.bashrc`, `cp evil ~/.profile`, `dd if=evil of=~/.bashrc` — shell file operands and redirect targets are run through `ClassifyPath`, so writes to shell rc files, `~/.ssh`, `~/.odek` trust anchors, and other home-sensitive paths are `system_write` instead of auto-allowed `local_write`. Home credential files (`~/.netrc`, `~/.npmrc`, `~/.pypirc`, `~/.pgpass`, `~/.git-credentials`, `~/.my.cnf`, `~/.cargo/credentials`, `~/.gem/credentials`, `~/.azure/credentials`, `~/.password-store`, `~/.terraform.d`, `~/.vault-token`) classify the same way for file-tool writes and for shell reads (`cat ~/.npmrc` is not `safe`). Matching is case-insensitive across full path components, so `~/.SSH/id_rsa`, `~/.AWS/credentials`, and `~/.ODEK/config.json` escalate on case-insensitive filesystems (macOS APFS, Windows NTFS). diff --git a/internal/danger/classifier.go b/internal/danger/classifier.go index 43013b8f..e51b8a62 100644 --- a/internal/danger/classifier.go +++ b/internal/danger/classifier.go @@ -5224,6 +5224,8 @@ var gitProgramOptions = []string{"upload-pack", "receive-pack", "exec", "templat // --template). func gitRunsProgramOption(sub string, args []string) bool { switch sub { + case "send-email": + return gitSendEmailRunsProgram(args) case "clone", "fetch", "pull", "ls-remote", "push", "fetch-pack", "send-pack", "archive", "init": default: @@ -5260,6 +5262,54 @@ func gitRunsProgramOption(sub string, args []string) bool { return false } +// gitSendEmailCommandOptions are the send-email options whose value is a +// command git runs (Getopt::Long accepts unambiguous prefixes, so a prefix of +// at least four characters counts). +var gitSendEmailCommandOptions = []string{"sendmail-cmd", "to-cmd", "cc-cmd", "header-cmd"} + +// gitSendEmailRunsProgram reports whether git send-email arguments name a +// program to run: a *-cmd option, or an --smtp-server value that is a path +// (git runs a path-valued SMTP server as a sendmail-like program; a host name +// carries no slash). +func gitSendEmailRunsProgram(args []string) bool { + for i := 0; i < len(args); i++ { + a := args[i] + if a == "--" { + return false + } + if !strings.HasPrefix(a, "--") { + continue + } + name, value, hasValue := strings.Cut(a[2:], "=") + for _, opt := range gitSendEmailCommandOptions { + if len(name) >= 4 && strings.HasPrefix(opt, name) { + return true + } + } + if name != "smtp-server" { + continue + } + if !hasValue { + if i+1 >= len(args) { + return true + } + i++ + value = args[i] + } + if gitSMTPServerIsProgram(value) { + return true + } + } + return false +} + +// gitSMTPServerIsProgram reports whether an smtp-server value names a program +// rather than a host: anything path-shaped, empty, or only known at run time. +func gitSMTPServerIsProgram(value string) bool { + return value == "" || strings.ContainsAny(value, "/~$`\\") || strings.HasPrefix(value, ".") || + hasDynamicSubstitution(value) +} + // isGitCodeExecution reports whether a git invocation carries a config override // or subcommand that can execute arbitrary shell code.

(Force-push is `system_write` rather than auto-allowed `network_egress`.) Hooks, filters, editors, configured filesystem monitors and diff/merge drivers carry execution risk, and the escalation is repository-aware: `git status`, `add`, `commit`, `merge`, `gc`, `stash`, `restore`, `diff`, checkout/switch, rebase, cherry-pick, am, worktree/submodule mutations, and the verbs that refresh the index, compare the work tree or move objects (`revert`, `reset`, `clean`, `rm`, `mv`, `update-index`, `diff-files`, `diff-index`, `ls-files`, `grep`, `blame`, `describe`, `checkout-index`, `pull`, `fetch`, `push`) are `code_execution` only when the repository they target (the tracked cwd, `git -C`, `--git-dir`, or the nearest `.git` directory or gitfile, including linked worktrees and cloned submodules) is armed for that verb: an executable real hook script (not `*.sample`) or `core.hooksPath`/`hook.*.command`, `core.fsmonitor` naming a program, a `filter.*` clean/smudge/process command (plain `git-lfs` filters excepted), `diff.external` or a `diff.*` command/textconv driver, a `merge.*` driver, or an editor for a verb that opens one (`commit` without `-m`/`-F`/`-C`, `merge` without `--no-edit`, `rebase -i`), found in the repository, global or system git config, or the process environment. Config files are parsed minimally without following includes (an `include`/`includeIf` section counts as armed); an uncertain cwd, a missing or unreadable repository, hooks directory or config, an oversized config, or `GIT_DIR`-style environment overrides fail closed to `code_execution`. Command-line escalations are unconditional: `-c`/`--config-env` exec keys (including `include.path`), `--ext-diff`/`--textconv`, `--paginate`, `rebase --exec`, external merge strategies, `difftool`/`mergetool`, `bisect run`, `hook run` and `submodule foreach`. Unarmed, these verbs classify by their other effects (so `git checkout -- .` stays `system_write` and remote verbs stay `network_egress`).

A `for` over a static word list is analysed once per element with the loop variable bound to it (`for d in / /etc; do rm -rf "$d"; done` is `destructive`, `for f in a b` is `local_write`); a glob, `$VAR`, `$(…)` or a list over 64 words binds the variable to the dynamic marker, so a dangerous verb on it fails closed as `unknown`. Words after `in` and case patterns are data scanned as resource tokens, never commands. Subshells restore the caller's variables and directory; branches and loop bodies join their state with the state before them and forget whatever they changed; a function body is judged where it is defined and again at each same-command call, with the call's arguments bound to `$1`…`$9`, `"$@"` and `"$*"`. A construct the parser cannot pair (missing `done`/`fi`/`)`/`}`, a stray `then`/`do`, a case pattern list or `for` list holding an operator) classifies `unknown` while the commands inside it are still judged; `[[ … ]]` and `(( … ))` are data, but each clause that would be a command were the bracket only a word is classified too, so an escaped bracket cannot hide one.

Nested backticks are unescaped one level at a time. - `rm$IFS-rf$IFS/`, `{rm,-rf,/}`, `/et{c..c}/shadow` — `$IFS` and brace expansion are normalised: comma groups distribute their preamble and postscript, and `{x..y[..step]}` sequences (`{1..3}`, `{a..c}`) expand under size caps. `$((…))` is arithmetic (substitutions nested inside it are still extracted), a backslash-newline joins lines, comments are stripped, and an empty positional parameter glued into a word vanishes. A here-document body that feeds a data-only program is consumed as data, while substitutions inside an unquoted body are still classified. -- `command rm`, `env rm`, `sudo rm`, `/bin/rm`, `true | dd of=/dev/sda` — wrappers are stripped, every pipe stage is classified, and basenames select adapters while original executable paths remain intact.

Inert values (`NODE_ENV=production`, `ENV=production ls`, `SHELL=/bin/bash echo hi`, `GIT_TRACE2=1`, `CFLAGS=-O2`) are unchanged. `export NAME=…` of an exec-controlling name (`PATH`, `LD_PRELOAD`, `GIT_CONFIG_COUNT` and its `KEY_n`/`VALUE_n`, `JAVA_TOOL_OPTIONS`, `LESSOPEN`, `SSH_ASKPASS`, …) escalates the same way, since it arms every later command in the session; other exports (`export FOO=bar`) are inert. - `rm ${X:--rf} /` — default-value parameter expansions that expand to rm flags are fail-closed. diff --git a/internal/danger/analysis.go b/internal/danger/analysis.go index da0bb1af..38f75f7c 100644 --- a/internal/danger/analysis.go +++ b/internal/danger/analysis.go @@ -345,6 +345,14 @@ func analyzeWithState(cmd string, depth int, inherited *shellAnalysisState) Anal if name == "eval" && len(inner) > 1 { result.merge(analyzeWithState(strings.Join(inner[1:], " "), depth+1, &payloadState)) } + // sh expands aliases on later lines, so an alias body runs + // under the alias name: classify each definition as the + // command it would run. + if name == "alias" { + for _, body := range aliasBodies(inner[1:]) { + result.merge(analyzeWithState(body, depth+1, &payloadState)) + } + } } if i > 0 { pipeline = append(pipeline, "|") @@ -1256,6 +1264,22 @@ func resolveInDirectory(path, cwd string) string { return path } +// aliasBodies returns the bodies of the NAME=BODY definitions among alias +// arguments.

The command word now skips time/! prefixes and the guard covers only the expansion text itself.

A `for` over a static word list is analysed once per element with the loop variable bound to it (`for d in / /etc; do rm -rf "$d"; done` is `destructive`, `for f in a b` is `local_write`); a glob, `$VAR`, `$(…)` or a list over 64 words binds the variable to the dynamic marker, so a dangerous verb on it fails closed as `unknown`. Words after `in` and case patterns are data scanned as resource tokens, never commands. Subshells restore the caller's variables and directory; branches and loop bodies join their state with the state before them and forget whatever they changed; a function body is judged where it is defined and again at each same-command call, with the call's arguments bound to `$1`…`$9`, `"$@"` and `"$*"`. A construct the parser cannot pair (missing `done`/`fi`/`)`/`}`, a stray `then`/`do`, a case pattern list or `for` list holding an operator) classifies `unknown` while the commands inside it are still judged; `[[ … ]]` and `(( … ))` are data, but each clause that would be a command were the bracket only a word is classified too, so an escaped bracket cannot hide one. Nesting is capped at 32 levels and repeated loop passes draw on the shared token budget. - `\rm -rf /`, `r""m -rf /`, `$'\x72\x6d' -rf /` — normalization is quote-aware: backslash escapes are collapsed outside quotes and stay inert inside single quotes, quote boundaries are not word boundaries, and ANSI-C `$'…'` strings (`\x`, octal, `\u`/`\U` and the usual control escapes) decode to a quoted literal instead of splicing decoded bytes back in as shell syntax. Nested backticks are unescaped one level at a time. - `rm$IFS-rf$IFS/`, `{rm,-rf,/}`, `/et{c..c}/shadow` — `$IFS` and brace expansion are normalised: comma groups distribute their preamble and postscript, and `{x..y[..step]}` sequences (`{1..3}`, `{a..c}`) expand under size caps. `$((…))` is arithmetic (substitutions nested inside it are still extracted), a backslash-newline joins lines, comments are stripped, and an empty positional parameter glued into a word vanishes.

Only an element flagged by itself carries the security notice. Ingests are recorded per chunk of at most 64 elements, matching the audit store's per-record resource cap, so the hash and resource list still cover every element and every discovered path stays on a record; the per-element wrapper sources remain in the tool message that divergence detection reads. Appends to the audit log validate the file (legacy JSON, symlink, directory, torn tail, corruption) on the first append of a process and whenever the file is no longer exactly as the previous append left it (inode, size or mtime changed); steady-state appends are a single `O_APPEND` write, and a last line without its newline always gets one before the next record. -After each turn, odek records the tools called and runs a divergence heuristic: a turn is flagged `suspicious_divergence` when the agent ingested untrusted content **and** the agent's actions or final response reference resources that either (a) did not appear in the user's preceding message, or (b) were introduced by the untrusted content itself.
