Openclaw: >> Openclaw >> 2026.5.6 Security Vulnerabilities
OpenClaw before 2026.5.26 contains an authorization bypass vulnerability where a surviving pairing-scoped device session can re-establish node token authority after revocation. Attackers with a paired device can regain WebSocket node-level access without renewed approval, weakening revocation controls and maintaining unauthorized access longer than intended.

OpenClaw before 2026.5.6 contains a privilege escalation vulnerability in the Active Memory write scope that allows Gateway operators with operator.write access to modify global configuration without requiring operator.admin privileges. Attackers with operator.write access can exploit insufficient scope validation to apply unauthorized configuration changes beyond the intended write scope.

OpenClaw before 2026.5.12 contains an information disclosure vulnerability in streamable-http MCP servers that forwards operator-configured custom headers during cross-origin redirects. Attackers controlling or compromising an MCP endpoint can redirect requests to exfiltrate sensitive headers like API keys or tenant-routing credentials to attacker-controlled origins.

OpenClaw before 2026.5.12 contains an allowlist bypass vulnerability in PowerShell encoded-command handling that allows attackers to execute encoded commands using abbreviated flag aliases not recognized by the allowlist parser. Remote authenticated operators can bypass execution allowlist checks by using unrecognized encoded-command alias forms to execute arbitrary PowerShell content.
