GHSA-39pp-xp36-q6mg OpenClaw has Inconsistent Host Exec Environment Override Sanitization

• npm openclaw: < 2026.3.22 → fixed in 2026.3.22

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 • 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.
