OpenClaw versions prior to 2026.2.22 contain an allowlist bypass vulnerability in system.run that allows attackers to execute non-allowlisted commands by splitting command substitution using shell line-continuation characters. Attackers can bypass security analysis by injecting $\\ followed by a newline and opening parenthesis inside double quotes, causing the shell to fold the line continuation into executable command substitution that circumvents approval boundaries.

Ein Angreifer kann mehrere Schwachstellen in OpenClaw ausnutzen, um beliebigen Code auszuführen, sich erhöhte Berechtigungen zu verschaffen, Daten zu manipulieren, einen Denial-of-Service-Zustand herbeizuführen, Sicherheitsmaßnahmen zu umgehen, vertrauliche Informationen offenzulegen oder andere nicht näher spezifizierte Angriffe durchzuführen.
- GHSA-9868-vxmx-w862OpenClaw's system.run allowlist bypass via shell line-continuation command substitution2026-03-03ghsa · osvUS
### Summary In OpenClaw `system.run` allowlist mode, shell-wrapper analysis could be bypassed by splitting command substitution as `$\\` + newline + `(` inside double quotes. Analysis treated the payload as allowlisted (for example `/bin/echo`), while shell runtime folded the line continuation into `$(...)` and executed non-allowlisted subcommands. ### Affected Packages / Versions - Package: npm `openclaw` - Latest published affected version: `2026.2.21-2` - Affected range: `<=2026.2.21-2` - Patched version (planned next release): `2026.2.22` ### Impact In deployments that opt into `tools.exec.security=allowlist` (with `ask=on-miss` or `off`), this can bypass approval boundaries and lead to unintended command execution. ### Fix Commit(s) - `3f0b9dbb36c86e308267924c0d3d4a4e1fc4d1e9` ### Remediation - Upgrade to `2026.2.22` (or newer) when published. - Temporary mitigation: set `tools.exec.ask=always` or `tools.exec.security=deny`. ### Release Process Note `patched_versions` is pre-set to planned next release `2026.2.22`. After npm release is out, this advisory should be ready for direct publish without additional metadata edits. OpenClaw thanks @tdjackey for reporting.
