CVE-2026-73611
MediumCVSS 6.8Exploitation Probability (EPSS)
Low risk19th percentile - higher than 19% of all known CVEs
Summary
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.
Risk Assessment
A person with an outdated token can maintain unlimited access to the administrative panel, potentially leading to unauthorized data access and system takeover.
Recommendation
It is recommended to upgrade File Browser to a version newer than 2.63.21 that includes the JWT expiration validation fix, and consider changing the logout page configuration.
