OpenClaw < 2026.5.2 - Credential Exposure via Model-Supplied Loopback URLs in message.action Forwarding

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.
