Security Vulnerabilities
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.

OpenClaw before 2026.5.2 contains a credential exposure vulnerability in message.action forwarding that allows model-controlled metadata to forward action payloads with Gateway credentials to attacker-supplied loopback URLs. Remote attackers can intercept Gateway tokens and action payloads by providing malicious loopback targets through model-controlled action metadata.

OpenClaw before 2026.5.18 contains an identity header validation vulnerability allowing local same-host callers to forge trusted-proxy identity headers. Attackers with access to the proxy-facing Gateway port can supply forged identity headers to assume operator identity and potentially escalate privileges.
