CVE-2026-35666
OpenClaw's system.run allowlist can be bypassed through an unregistered time dispatch wrapper
Description
## Summary Allow-always exec approvals did not unwrap /usr/bin/time, so an unregistered time wrapper could bypass executable binding and reuse approval state for the inner command. ## Affected Packages / Versions - Package: `openclaw` (npm) - Affected: < 2026.3.22 - Fixed: >= 2026.3.22 - Latest released tag checked: `v2026.3.23-2` (`630f1479c44f78484dfa21bb407cbe6f171dac87`) - Latest published npm version checked: `2026.3.23-2` ## Fix Commit(s) - `39409b6a6dd4239deea682e626bac9ba547bfb14` ## Release Status The fix shipped in `v2026.3.22` and remains present in `v2026.3.23` and `v2026.3.23-2`. ## Code-Level Confirmation - src/infra/dispatch-wrapper-resolution.ts now unwraps /usr/bin/time and binds approvals to the real inner executable. - src/infra/exec-approvals-allow-always.test.ts ships regression coverage for time-wrapper allow-always approval bypasses. OpenClaw thanks @YLChen-007 for reporting.
