OpenClaw before 2026.5.6 contains an allowlist bypass vulnerability in the macOS Swift exec feature that misses combined POSIX inline-command flags. Attackers can execute shell content outside the intended allowlist check by using combined flag forms, potentially allowing unauthorized command execution depending on operator configuration.

- WID-SEC-W-2026-1738OpenClaw: Mehrere SchwachstellenDeutsch2026-05-28csaf · cert_bundDE
Ein entfernter, authentisierter Angreifer kann mehrere Schwachstellen in OpenClaw ausnutzen, um Sicherheitsmechanismen zu umgehen, erhöhte Berechtigungen zu erlangen, Informationen offenzulegen, Konfigurationen zu manipulieren, beliebige Befehle oder Code auszuführen sowie interne Systeme über SSRF anzugreifen.
- GHSA-c226-q6fx-6j6cOpenClaw: macOS Swift exec allowlist missed combined POSIX inline flags2026-06-18ghsa · osvUS
### Summary macOS Swift exec allowlist missed combined POSIX inline flags. In affected versions, a command request using combined POSIX inline-command flags could miss inline-command content expressed through combined flags. This advisory is scoped to the named feature and configuration. It does not change OpenClaw's trusted-operator model: authenticated Gateway operators, installed plugins, and intentional local execution surfaces remain trusted unless a separate policy, approval, allowlist, sandbox, or auth boundary is crossed. ### Impact When the affected feature is enabled and reachable, this could run shell content outside the intended allowlist check. Practical impact depends on the operator's configuration and whether lower-trust input can reach that path. ### Patched Versions The first stable patched version is `2026.5.6`. ### Mitigations require approval for combined shell flag forms on macOS until patched. As general hardening, keep channel and tool allowlists narrow, avoid sharing one Gateway between mutually untrusted users, and disable the affected feature when it is not needed.
