CVE-2026-53819

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.

### Summary Workspace .env could override Homebrew executable selection for skill install flows. In affected versions, a workspace `.env` in a repository opened by a trusted operator could override the Homebrew executable used by the install helper. 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 an unintended Homebrew-compatible executable during skill setup. 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 `2026.5.27`. ### Mitigations avoid running skill install flows from untrusted workspaces 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.
