- GHSA-39pp-xp36-q6mgOpenClaw has Inconsistent Host Exec Environment Override Sanitization2026-03-26ghsa · osvUS
## Summary Gateway host exec env override handling did not consistently apply the shared host environment policy, so blocked or malformed override keys could slip through inconsistent sanitization paths. ## 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) - `7abfff756d6c68d17e21d1657bbacbaec86de232` ## 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/host-env-security.ts now provides one shared sanitizer and fail-closed diagnostics for blocked or malformed override keys. - src/agents/bash-tools.exec.ts and src/node-host/invoke-system-run.ts both route env overrides through the shared sanitizer before execution. OpenClaw thanks @zpbrent for reporting.
