Detailsinfo

A vulnerability classified as problematic has been found in FreshRSS up to 1.27.x. Affected is the function mt_rand/uniqid of the component Challenge-Response Handler. The manipulation with an unknown input leads to a weak prng vulnerability. CWE is classifying the issue as CWE-338. The product uses a Pseudo-Random Number Generator (PRNG) in a security context, but the PRNG's algorithm is not cryptographically strong. This is going to have an impact on confidentiality. CVE summarizes:

FreshRSS is a free, self-hostable RSS aggregator. Prior to version 1.28.0, FreshRSS uses cryptographically weak random number generators (mt_rand() and uniqid()) to generate remember-me authentication tokens and challenge-response nonces. This allows attackers to predict valid session tokens, leading to account takeover through persistent session hijacking. The remember-me tokens provide permanent authentication and are the sole credential for "keep me logged in" functionality. This issue has been patched in version 1.28.0.

The advisory is available at github.com. This vulnerability is traded as CVE-2025-68932 since 12/25/2025. The exploitability is told to be difficult. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. Technical details are known, but there is no available exploit. This vulnerability is assigned to T1600.001 by the MITRE ATT&CK project.

Upgrading to version 1.28.0 eliminates this vulnerability. Applying the patch 57e1a375cbd2db9741ff19167813344f8eff5772 is able to eliminate this problem. The bugfix is ready for download at github.com. The best possible mitigation is suggested to be upgrading to the latest version.
