CVE-2026-100566

Estado: AplazadaMedia (6.9)—

OpenClaw LINE versions before 2026.8.1 contain an access control vulnerability where group allowlist mode silently inherits DM allowFrom values when groupAllowFrom is not explicitly configured. Attackers with group participation can trigger the agent despite configured group allowlist restrictions when DM access is broader than intended group access.

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.

Vulnerabilidad de control de acceso (CWE-863) en servicio remoto OpenClaw que permite a atacantes con participación en grupo eludir restricciones de allowlist mediante herencia silenciosa de valores DM, resultando en acceso no autorizado. Vector AV:N/PR:N confirma explotación remota sin privilegios.

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.
