CVE-2025-54592

Estado: AnalizadaAlta (8.8)—

FreshRSS is a free, self-hostable RSS aggregator. Versions 1.26.3 and below do not properly terminate the session during logout. After a user logs out, the session cookie remains active and unchanged. The unchanged cookie could be reused by an attacker if a new session were to be started. This failure to invalidate the session can lead to session hijacking and fixation vulnerabilities. This issue is fixed in version 1.27.0

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.

AV:N/PR:N/UI:N indica exposición en red sin autenticación previa. La cookie activa tras logout permite reutilización de sesión válida (hijacking), ganando acceso como usuario autenticado (T1078). El atacante podría alterar preferencias o datos del usuario (T1556).

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.
