Description

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

Affected products

• FreshRSS: before 1.27.0 — fixed in 1.27.0

How to fix

Upgrade to a fixed version: FreshRSS 1.27.0. Check the vendor advisory for mitigations.
