AnalysisAIv1 – Mar 12, 2026

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.

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.

Executive ViewAI

Why It Matters

OpenClaw versions prior to 2026.1.29 contain a critical flaw that allows attackers to hijack WebSocket connections and steal authentication tokens by manipulating query parameters. Organizations using affected versions face immediate risk of unauthorized access, session hijacking, and potential lateral movement within connected systems.

Business Impact: High

Compensating Controls

Implement Web Application Firewall (WAF) rules to block WebSocket connections with untrusted or suspicious gatewayUrl parameters in query strings; enforce network segmentation to restrict OpenClaw instances from initiating outbound connections except to hardcoded, pre-approved gateway servers; disable WebSocket functionality entirely if not business-critical; implement token rotation policies with shortened expiration windows; deploy real-time monitoring and alerting on unexpected WebSocket connection attempts; require mutual TLS (mTLS) for all gateway connections to prevent token exfiltration.
