Issue for this PR

Closes #1245

Type of change

  • Bug fix

What does this PR do?

Security-relevant / expedited — please review promptly. origin/main's TypeScript CI job has been red since ~2026-09-04 07:28Z, blocking all PRs. This fixes both the broken-main failure and a live credential-leak regression it's coupled to.

Root cause: #1117 (14ba9bb9e7) added a filesystem-path masking rule to Telemetry.maskString (packages/opencode/src/altimate/telemetry/index.ts). SessionCompaction.redactLedgerDetail (packages/opencode/src/session/compaction.ts) calls Telemetry.maskString(value) before running its own -u/--user curl-credential redaction. That ordering has two consequences:

  1. Over-masking (4 of the 5 failing tests): every write path (2+ path segments) collapses to the literal <path>, so the session ledger — whose whole purpose is to tell the model which files it already wrote — can no longer report file paths at all.
  2. Credential leak (the 5th test, and the important one): when curl is invoked path-qualified (/usr/bin/curl -u alice password ...), maskString's path rule replaces the curl/curl.exe token with <path> before redactLedgerDetail's curl-context lookback ever runs. With the curl token gone, the lookback can't find it, curlContext comes back false, and the space-separated (non-colon-shaped) -u alice password idiom isn't otherwise recognized as credential-shaped — so it passes through redactLedgerDetail completely unredacted. This ledger text is persisted into a later model prompt across compaction (see the comment at compaction.ts:~657): a real credential leaking across a session/provider boundary.

The leak is main-only — not present in v0.10.0 or any released version.

Fix:

  1. Telemetry.maskString gains an opt-out for its path-masking pass: maskString(value, opts?: { maskPaths?: boolean }), default maskPaths: true — byte-for-byte unchanged for every existing caller. When maskPaths: false, only the fix: mask filesystem paths in telemetry error text #1117 path rule is skipped; every other mask (api keys, bearer tokens, emails, internal hosts, quote collapsing) still applies.
  2. redactLedgerDetail now calls maskString(value, { maskPaths: false }). This restores write-path fidelity (fixes the 4 over-mask tests), and — because the curl token survives — the curl-context lookback works again, closing the leak (fixes the 5th test).
  3. Belt-and-suspenders: redactLedgerDetail's curl-context detection is also derived independently from the pre-mask raw value (correlated ordinally against the masked-string matches, with a safe fallback to the prior masked-only check if the two ever disagree). This makes curl detection structurally immune to any future masking rule that happens to eat the command-name token — it no longer depends solely on maskPaths: false.
  4. No other maskString call site was touched — they all keep maskPaths: true (mcp/index.ts, sql-execute.ts, tool.ts, prompt.ts, register.ts, dispatcher.ts, registry.ts, warehouse-add.ts, project-scan.ts). fix: mask filesystem paths in telemetry error text #1117's telemetry path-masking protection is fully intact for its intended consumers — verified by test/telemetry/mask-file-paths.test.ts staying green.

Both telemetry/index.ts and compaction.ts are upstream-shared files; edits are wrapped in altimate_change markers. The marker guard (bun run script/upstream/analyze.ts --markers --base origin/main --strict) reports clean.

Related: this touches the same session-state-ledger security work referenced in compaction.ts (redactLedgerDetail's existing credential-redaction suite).

How did you verify your code works?

  • bun test packages/opencode/test/session/compaction-ledger.test.ts packages/opencode/test/session/compaction-ledger-history.test.ts — 54 pass, 0 fail (was 5 failing on main).
  • Added an explicit adversarial test reproducing the exact leak shape: redactLedgerDetail("/usr/bin/curl -u alice hunter2 https://example.com") and a /usr/local/bin/curl.exe variant, asserting the output contains neither alice nor hunter2. Confirmed it fails against pre-fix code via git stash on the two source files (leaving the new test in place) — reproduced the leak verbatim (<path> -u alice hunter2 https://example.com/) — then confirmed it passes after git stash pop.
  • bun test test/telemetry/mask-file-paths.test.ts test/altimate/telemetry-signals.test.ts test/mcp/mcp-bearer-auth.test.ts — 211 pass, 0 fail (confirms fix: mask filesystem paths in telemetry error text #1117's default-maskPaths path masking is untouched for its other callers).
  • Broader regression sweep: bun test across all test/session/compaction-*.test.ts, observation-mask, task-pin, uncounted-tail — 241 pass, 0 fail, 0 regressions.
  • bun run typecheck — clean across all 15 workspace packages.
  • bun run script/upstream/analyze.ts --markers --base origin/main --strict — clean.
  • Pushed and confirmed the TypeScript CI job goes green on the pushed commit.

Not independently re-verified: the pre-existing flaky timeouts in test/session/prompt.test.ts (loop calls LLM and returns assistant message, loop surfaces content-filter finishes as session errors) — confirmed these fail identically against unmodified origin/main (network/mock-provider timeout issue, unrelated to this change) and are not part of this PR's scope.

Note

High Risk
Changes credential redaction on compaction ledger text that is persisted into later model prompts; the fix is targeted but security-critical.

Overview
Fixes a credential leak and ledger over-masking caused by running filesystem path masking on session-ledger text before compaction-specific redaction.

Telemetry.maskString now accepts optional { maskPaths?: boolean } (default true), so only the #1117 path pass can be skipped; API keys, bearer tokens, emails, and other rules are unchanged for existing callers. redactLedgerDetail calls maskString(value, { maskPaths: false }) so write paths stay visible in the state ledger and path-qualified commands like /usr/bin/curl are not collapsed to <path> before curl-context detection.

Hardening: -u/--user handling uses a shared USER_FLAG_RE, and curl context is inferred from both the masked string and the raw pre-mask value (ordinal-aligned), so a future mask rule that strips curl is less likely to reopen the leak.

Adds a regression test for path-qualified curl with space-separated -u user password.

Summary by cubic

Fixes a credential leak and broken write-path reporting in the session ledger that #1117 introduced. Telemetry.maskString's new path-masking pass collapsed /usr/bin/curl to <path> before redactLedgerDetail's curl-context lookback ran, so path-qualified curl -u user password leaked unredacted into ledger text persisted across compaction; write paths also collapsed to <path>, breaking the ledger's file-reporting purpose. The leak is main-only, not in any release, and the change fixes the five tests that have been red on origin/main's TypeScript CI since ~2026-09-04 07:28Z.

Bug Fixes

  • Telemetry.maskString gains a maskPaths opt-out (default true, byte-for-byte unchanged for all existing callers); only the path pass is skipped, all other masks still apply.
  • redactLedgerDetail now calls maskString(value, { maskPaths: false }), restoring write-path fidelity and the curl-context lookback.
  • Curl-context detection is also derived from the raw pre-mask value (ordinally correlated with the masked matches), so a future mask rule that eats the command token can't reopen the leak.
  • Adds regression tests for path-qualified curl and curl.exe with space-separated -u user password, confirmed failing against pre-fix code.

Written for commit 3463f09. Summary will update on new commits.

Review in cubic

…ential leak introduced by #1117

`SessionCompaction.redactLedgerDetail` called `Telemetry.maskString` before
its own curl-credential redaction. #1117 added a filesystem-path masking
pass to `maskString` that collapses any 2+ segment path — including
`/usr/bin/curl` — to the literal `<path>` before the curl-context lookback
ran. Two consequences:

- Every write path in the ledger collapsed to `<path>`, so the ledger could
  no longer report which file was written (4 failing tests).
- With the `curl` token gone, the curl-context lookback found nothing, so a
  path-qualified curl invocation's space-separated `-u user password`
  (non-colon-shaped, so not otherwise flagged as credential-shaped) passed
  through `redactLedgerDetail` unredacted — a real credential leaking into
  ledger text that is later persisted into a model prompt across compaction.

Fix:
- `Telemetry.maskString` gains an opt-out for its path-masking pass
  (`maskPaths`, default `true`, unchanged for every existing caller). Every
  other mask (api keys, bearer tokens, emails, internal hosts, quote
  collapsing) still applies regardless.
- `redactLedgerDetail` calls `maskString(value, { maskPaths: false })`,
  restoring write-path fidelity and, because the `curl` token survives,
  restoring the curl-context lookback.
- Belt-and-suspenders: `redactLedgerDetail`'s curl-context detection is also
  derived independently from the pre-mask raw value (correlated ordinally
  against the masked-string matches), so it no longer depends solely on
  `maskPaths:false` — a future masking rule that happens to eat the command
  name can't quietly reopen this leak.

Adds an explicit adversarial test reproducing the leak
(`/usr/bin/curl -u alice hunter2 ...` and the `curl.exe` path-qualified
variant); confirmed it fails against pre-fix code via `git stash` and passes
after. #1117's own telemetry path-masking is untouched for its other callers
(mcp/index.ts, sql-execute.ts, tool.ts, prompt.ts, register.ts, dispatcher.ts,
registry.ts, warehouse-add.ts, project-scan.ts) — confirmed via
test/telemetry/mask-file-paths.test.ts still green.

Fixes broken main: origin/main's TypeScript CI job has been red since
~2026-09-04 07:28Z on these 5 tests, blocking all PRs. The leak itself is
main-only — not present in v0.10.0 or any released version.

📝 Walkthrough

Walkthrough

Telemetry masking now supports disabling path masking for ledger redaction. Session compaction detects path-qualified curl commands and redacts space-separated credentials. A regression test covers POSIX and Windows curl paths.

Changes

Ledger redaction

Layer / File(s) Summary
Configurable telemetry path masking
packages/opencode/src/altimate/telemetry/index.ts
maskString and pmMask accept maskPaths and preserve all other masking rules when path masking is disabled.
Path-qualified curl credential redaction
packages/opencode/src/session/compaction.ts, packages/opencode/test/session/compaction-ledger.test.ts
Ledger redaction preserves curl tokens, detects path-qualified curl and curl.exe commands, correlates raw and masked occurrences, and tests space-separated credential redaction.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟠 High · up to 3463f

The change improves path-qualified curl redaction, but quoted Windows executable paths can still expose usernames and passwords in persisted session ledgers. This credential leak should be fixed before merge.

P1 Badge Bound raw curl scanning to the redaction window

When a tool command is large and contains many -u/--user occurrences, this scans the entire unbounded raw value and calls shellSegmentBefore from the beginning for every match, making redaction quadratic in the command length. callDetail passes command inputs here without slicing, so a sufficiently large generated command can stall compaction even though Telemetry.maskString deliberately caps its work at 8 KiB; limit the raw scan to the same retained window or compute shell context in a single pass.

P2 Badge Ignore quoted curl text when classifying user flags

When a non-curl command has a quoted argument containing the standalone word curl before a benign -u/--user, the new raw signal treats that quoted text as curl execution and redacts the flag value. For example, docker run --label 'use curl here' -u 1000:1000 alpine now loses the UID:GID that the surrounding logic explicitly preserves; the prior masked-only check did not do this because quoted spans were collapsed first. Derive the raw context with quote-aware tokenization rather than applying isCurlContext to a segment that still contains quoted arguments.

// path-qualified `curl -u user password` credential slips through

P1 Badge Retain path masking for replayed observation details

When a cleared tool's arguments or first output line contains an unquoted home or client path, disabling path masking here now copies that path into createObservationMask. That mask explicitly replaces the cleared output and is replayed on every later provider request, so values such as /Users/Jane Doe/client-repo/... can survive clearing and be disclosed after a provider switch. Preserve paths only for the ledger write entries that require them rather than disabling the PII path pass in the shared redactor used by observation masks.
