What is CVE-2026-25889?

A case-sensitivity flaw in the password validation logic of File Browser allows any authenticated user to change their password without entering the current password. This issue stems from the misuse of Title Case for the 'Password' field in API requests, which bypasses the verification of 'current_password.' An attacker who has gained valid JWT tokens through cross-site scripting (XSS) or session hijacking can exploit this vulnerability to take over user accounts. The flaw has been addressed in version 2.57.1.
