CVE-2026-86723

Estado: AplazadaAlta (8.6)—

AVideo through c3edcc274c389816d434acadac07ee78eaf330c1 contains an authentication bypass vulnerability in LoginControl::verifyChallenge() that uses loose comparison (==) instead of strict comparison (===) against unset session values. Attackers with only a password can submit an empty request to verifyChallenge.json.php to bypass PGP two-factor authentication and gain full authenticated 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.

Acceso de red con PR:L (atacante autenticado) a servicio remoto (LoginControl) para eludir 2FA mediante comparación laxa; obtiene acceso autenticado (T1078) y potencial escalada si hay funciones administrativas (T1068).

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.
