What is CVE-2025-54591?

FreshRSS is a self-hostable RSS aggregator that contains an access control vulnerability allowing exposure of default admin users' feed and tag information. This vulnerability arises from inadequate access checks in the FreshRSS_Auth::hasAccess() function. Specific endpoints related to tags and feeds fail to enforce proper access validation. While many controllers implement a defined firstAction() method to ensure access requirements, certain endpoints do not utilize this method or lack manual access checks entirely. It is crucial for users of FreshRSS to upgrade to version 1.27.0 or later to mitigate this issue.

Affected Version(s)

FreshRSS < 1.27.0
