Fail closed when Windows ACL checks cannot be verified for file and exec secret providers unless the provider explicitly opts into allowInsecurePath. Strip UTF-8 BOMs from file-backed secrets and document the trusted-path override.\n\nThanks @zhanggpcsu.
* test(security): add coverage tests before security fixes
- scan-paths.ts: 100% line coverage (new test file, previously zero)
- windows-acl.ts: 100% line coverage (SID bypass, whoami throw, no-user null return)
- external-content.ts: 99% (line 248 defensive overlap guard, unreachable)
- skill-scanner.ts: 93% (lines 293-294/330/571 are defensive guards for
future extensibility, unreachable with current rules/patterns)
200+ tests covering TOCTOU paths, cache invalidation, forced-file escapes,
dir-entry-cache hit, SID world-bypass, diacritic-strip fallback,
fullwidth homoglyph markers, and more.
* fix(security): 5 security hardening fixes in src/security/
scan-paths: default requireRealpath to false (safe). All production callers
already pass requireRealpath: true; default callers are now secure.
windows-acl: block world-equivalent SIDs (S-1-1-0 Everyone etc.) from being
added to trusted set via USERSID env var.
windows-acl: log resolveCurrentUserSid failures instead of bare catch{}.
audit-extra: wrap JSON.parse in readPluginManifestExtensions with try-catch.
Malformed package.json returns [] instead of crashing the audit.
audit-extra: depth guard in listWorkspaceSkillMarkdownFiles to prevent
resource exhaustion from deep symlink cycles.
audit-extra: 2s timeout on fs.realpath in collectWorkspaceSkillSymlinkEscapeFindings
to protect against hanging on slow/network filesystems.
audit-extra: warn about phantom entries in plugins.allow that don't match
any installed plugin (pre-approval exploitation vector).
media-understanding/types: add allowPrivateNetwork to transport overrides
(duplicate of PR #66967, required for tsgo to pass here).
* fix(security): address security review findings in audit-extra.async.ts
Issue 1 — Symlink escape audit bypass on realpath timeout:
When realpathWithTimeout returns null (timeout or failure), the previous code
called 'continue', silently skipping the escape check. An attacker with a
symlink to a slow/network filesystem could hang realpath to prevent escape
detection. Now treats unverifiable symlinks as potential escapes and includes
them in the finding.
Issue 2 — Malformed package.json hides extension entrypoints from deep scan:
readPluginManifestExtensions previously swallowed JSON.parse errors and
returned [], which a malicious plugin could exploit by crafting a malformed
package.json to hide its openclaw.extensions entrypoints from the deep code
scanner. Now re-throws the parse error (with cause) so the caller in
collectPluginsCodeSafetyFindings can surface a warn finding and alert the
user, while still scanning the plugin directory via getCodeSafetySummary.
* fix(security): address PR review findings (P1 + P2)
P1 — BFS realpath in listWorkspaceSkillMarkdownFiles lacks timeout:
Extract realpathWithTimeout to module scope so the BFS dequeue loop
uses the same 2 s guard as the outer escape-detection callers. Previously
only the per-workspace and per-skill-file realpaths had the timeout;
a hanging NFS/SMB directory entry inside the BFS could still block
indefinitely.
P1 (acknowledged limitation) — Promise.race leaves the underlying
fs.realpath call running after timeout. fs.realpath cannot be cancelled
once submitted to libuv. Callers are sequential (one await at a time),
so at most one worker thread is occupied; the OS will eventually time
out the stuck call. This is documented in the module-level JSDoc.
P2 — Phantom allowlist check incorrectly flags bundled plugin IDs:
listChannelPlugins() returns bundled channel plugin IDs (telegram,
discord, browser, etc.) that are never in stateDir/extensions.
Add bundledPluginIds exclusion so the phantom-entry finding is scoped
to user-installed extension IDs only.
P2 — Rename MAX_SYMLINK_DEPTH / depthGuard to MAX_TOTAL_DIR_VISITS /
totalDirVisits to accurately reflect that the guard caps total BFS
iterations (2_000 * 20 = 40_000), not per-path symlink depth.
* fix(security): clean up realpathWithTimeout timer and add regression tests
- Clear the timer handle when fs.realpath resolves before the deadline,
preventing timer accumulation during large audit runs with many files.
- Add .unref() on the timer so it cannot hold the process alive while
waiting on a potentially hanging NFS/SMB path.
Regression tests added for three audit-extra.async security fixes:
- manifest parse error: malformed plugin package.json surfaces
plugins.code_safety.manifest_parse_error (audit-extra.async.test.ts)
- phantom allowlist with bundled exclusion: bundled channel plugin IDs
are excluded from plugins.allow_phantom_entries warnings; non-installed
non-bundled IDs are correctly reported (audit-plugins-phantom.test.ts)
- unverifiable realpath escape: fs.realpath failure / timeout produces a
skills.workspace.symlink_escape finding with 'realpath timed out' in
the detail (audit-workspace-skill-escape.test.ts)
* chore(security): add TODO for structured logger in windows-acl resolveCurrentUserSid
console.warn is acceptable short-term but may be noisy on constrained
Windows hosts; note the follow-up in-code so it is not lost.
* chore: drop unrelated formatting churn from security PR
Restores extensions/memory-lancedb/config.ts and
src/agents/pi-embedded-helpers/errors.ts to their origin/main state.
These were line-wrap-only formatting changes with no relation to the
security fixes in this branch.
* fix(security): address Codex P2 review findings
1. Normalize plugins.allow entries through normalizePluginId before
phantom-entry filtering so that bundled plugin aliases and legacy IDs
are correctly excluded. Without this, valid allow entries that resolve
via alias normalization could generate false-positive phantom warnings.
2. Surface a skills.workspace.scan_truncated warn finding when the BFS
visit cap (MAX_TOTAL_DIR_VISITS) is hit mid-traversal. Previously the
scanner silently returned partial results, allowing escaped SKILL.md
symlinks in the unvisited tree to go undetected.
listWorkspaceSkillMarkdownFiles now returns {skillFilePaths, truncated}
and collectWorkspaceSkillSymlinkEscapeFindings emits the new finding
when truncated is true.
Regression test added for the truncation path using a mocked readdir
that fills the queue past the cap (40 001 fake entries) and a mocked
realpath for zero-I/O iteration speed.
