DescriptionCVE.org

OpenClaw (aka clawdbot or Moltbot) before 2026.1.29 obtains a gatewayUrl value from a query string and automatically makes a WebSocket connection without prompting, sending a token value.

AnalysisAI

OpenClaw versions prior to 2026.1.29 automatically establish WebSocket connections to attacker-controlled gateway URLs extracted from query strings, transmitting authentication tokens without user confirmation. This network-based vulnerability requires user interaction (clicking a malicious link) and allows attackers to hijack authenticated sessions and perform actions with the victim's privileges. Public exploit code exists for this high-severity flaw with no patch currently available.

Technical ContextAI
