CVE-2026-28458

Estado: AnalizadaAlta (7.4)—

OpenClaw version 2026.1.20 prior to 2026.2.1 contains a vulnerability in the Browser Relay (extension must be installed and enabled) /cdp WebSocket endpoint in which it does not require authentication tokens, allowing websites to connect via loopback and access sensitive data. Attackers can exploit this by connecting to ws://127.0.0.1:18792/cdp to steal session cookies and execute JavaScript in other browser tabs.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

UI:R y acceso local (loopback 127.0.0.1) requieren interacción del usuario para explotar. Los impactos son acceso a sesiones (cookies, T1078) y ejecución JavaScript en pestañas (T1059.007).

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.
