What is CVE-2025-54591?

CVE-2025-54591 is a high-severity missing authorization vulnerability in FreshRSS, published on 29 Sep 2025. An attacker can exploit it over the internet without logging in, with no action from the victim.

Official description

FreshRSS is a free, self-hostable RSS aggregator. Versions 1.26.3 and below expose information about feeds and tags of default admin users, due to lack of access checking in the FreshRSS_Auth::hasAccess() function used by some of the tag/feed related endpoints. FreshRSS controllers usually have a defined firstAction() method with an override to make sure that every action requires access. If one doesn't, then every action has to check for access manually, and certain endpoints use neither the firstAction() method, or do they perform a manual access check. This issue is fixed in version 1.27.0.
