      "value": "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"

Después de que un usuario cierra sesión, la cookie de sesión permanece activa e inalterada. La cookie inalterada podría ser reutilizada por un atacante si se iniciara una nueva sesión.
