CVE-2026-28468 Details
Description
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.
A vulnerability exists in OpenClaw versions 2026.1.29-beta.1 prior to 2026.2.14, allowing local attackers to bypass authentication on the sandbox browser bridge server. This server, which operates on a loopback TCP port, controls browser endpoints such as profiles and tabs. The lack of authentication enables attackers to access these endpoints and manipulate browser sessions. Exploitation allows for the enumeration of tabs, retrieval of WebSocket URLs, execution of JavaScript in page contexts, and exfiltration of cookies and session data from authenticated browser sessions.
Users are advised to upgrade to OpenClaw version 2026.2.14 or later, where this vulnerability has been patched. Alternatively, the sandboxed browser feature can be disabled.
