CVE-2026-28460

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.

### 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.
