NVD Description

Note: Versions mentioned in the description apply only to the upstream filebrowser package and not the filebrowser package as distributed by Minimos. See How to fix? for Minimos:latest relevant fixed versions and status.

File Browser versions from 2.50.0 through 2.63.21 fail to validate JWT expiration when proxy authentication is configured with a non-default logout page. Attackers with a previously valid token can access protected routes and administrative endpoints indefinitely, and exchange expired tokens for fresh ones via the renewal endpoint.
