GHSA-xgf2-vxv2-rrmg OpenClaw's shell startup env injection bypasses system.run allowlist intent (RCE class)

• npm openclaw: < 2026.2.22 → fixed in 2026.2.22

Summary `system.run` environment sanitization allowed shell-startup env overrides (`HOME`, `ZDOTDIR`) that can execute attacker-controlled startup files before allowlist-evaluated command bodies. Affected Packages / Versions • Package: `openclaw` (npm) • Affected: `= 2026.2.22` Technical Details In affected versions: • Env sanitization blocked many dangerous keys, but not startup-sensitive override keys (`HOME`, `ZDOTDIR`) in host exec env paths. • Shell-wrapper analysis for allowlist mode models command bodies, but not shell startup side effects. • Runtime execution used sanitized env, so attacker-provided startup-key overrides could run hidden startup payloads first. Observed exploit vectors: • `HOME` + `bash -lc` + malicious `.bash_profile` • `ZDOTDIR` + `zsh -c` + malicious `.zshenv` Fix Commit(s) • `c2c7114ed39a547ab6276e1e933029b9530ee906` Release Process Note `patched_versions` is pre-set to the planned next release (`>= 2026.2.22`). After the npm release is published, this advisory can be published directly. OpenClaw thanks @tdjackey for reporting.
