CVE-2025-54592: Freshrss

Critical severity, CVSS 9.8. EPSS: 0.5% chance of exploitation in the next 30 days.

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
