Technical ContextAI · show details
This vulnerability (CWE-306: Missing Authentication for Critical Function) affects Openclaw. OpenClaw versions 2026.1.5 prior to 2026.2.12 fail to enforce mandatory authentication on the /agent/act browser-control HTTP route, allowing unauthorized local callers to invoke privileged operations. Remote attackers on the local network or local processes can execute arbitrary browser-context actions and access sensitive in-session data by sending requests to unauthenticated endpoints.

Lifecycle Timeline
2DescriptionCVE.org
OpenClaw versions 2026.1.5 prior to 2026.2.12 fail to enforce mandatory authentication on the /agent/act browser-control HTTP route, allowing unauthorized local callers to invoke privileged operations. Remote attackers on the local network or local processes can execute arbitrary browser-context actions and access sensitive in-session data by sending requests to unauthenticated endpoints.
Executive ViewAI
Openclaw versions up to 2026.2.12 contain a critical authentication bypass vulnerability (CVSS 8.4) that could allow unauthorized actors to access sensitive functions without proper credentials. Organizations running affected versions face immediate risk of unauthorized data access, system manipulation, and potential operational disruption.
Apply vendor patch. If patching cannot be completed immediately: restrict network access to Openclaw instances using firewall rules and network segmentation; implement WAF rules to monitor for suspicious authentication bypass attempts; disable or restrict access to critical functions until patching is complete; enable comprehensive logging and monitoring for unauthorized access attempts.

Attack Technique
Authentication bypass attacks exploit flaws in the verification mechanisms that control access to systems and applications.
Remote Code Execution represents the critical moment when an attacker successfully runs arbitrary code on a target system without physical access.
