Technical ContextAI · show details
This vulnerability (CWE-306: Missing Authentication for Critical Function) affects Openclaw. OpenClaw versions 2026.1.29-beta.1 prior to 2026.2.14 contain a vulnerability in the sandbox browser bridge server in which it accepts requests without requiring gateway authentication, allowing local attackers to access browser control endpoints. A local attacker can enumerate tabs, retrieve WebSocket URLs, execute JavaScript, and exfiltrate cookies and session data from authenticated browser contexts.

Lifecycle Timeline
2DescriptionCVE.org
OpenClaw versions 2026.1.29-beta.1 prior to 2026.2.14 contain a vulnerability in the sandbox browser bridge server in which it accepts requests without requiring gateway authentication, allowing local attackers to access browser control endpoints. A local attacker can enumerate tabs, retrieve WebSocket URLs, execute JavaScript, and exfiltrate cookies and session data from authenticated browser contexts.
Executive ViewAI
Openclaw versions through 2026.2.14 contain a critical authentication bypass affecting core functions, allowing unauthorized users to access sensitive operations without valid credentials. This vulnerability poses immediate risk to any organization running affected versions and requires urgent patching to prevent unauthorized system access and potential data compromise.
Apply vendor patch. If immediate patching is unavailable: implement network-level access controls to limit Openclaw exposure, enable authentication logging and monitoring for anomalous access patterns, disable non-essential critical functions if technically feasible, and implement WAF rules to enforce authentication checks at the reverse proxy layer.
