Received Received - Intake
Authentication Bypass in OpenClaw /agent/act Enables Privileged Access

Publication date: 2026-03-05

Last updated on: 2026-03-11

Assigner: VulnCheck

Description
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 Summary

This vulnerability exists in OpenClaw versions 2026.1.5 prior to 2026.2.12, where mandatory authentication is not enforced on the /agent/act browser-control HTTP route.

Because of this, unauthorized local callers can invoke privileged operations without authentication.

Remote attackers on the local network or local processes can send requests to these unauthenticated endpoints to execute arbitrary browser-context actions and access sensitive in-session data.

Impact Analysis

This vulnerability can allow attackers who have local network access or local process access to execute privileged operations without authorization.

Attackers can perform arbitrary actions within the browser context and access sensitive data from active sessions.

This could lead to unauthorized data exposure, manipulation of browser sessions, and potential compromise of system integrity.
