CVE-2026-90930: Filebrowser

Medium severity, CVSS 6.8. EPSS: 0.5% chance of exploitation in the next 30 days.

File Browser through 2.63.23 applies path rules to the requested lexical path but resolves symbolic links without reapplying rules to the target, allowing authenticated users to bypass deny rules. Attackers can read and overwrite rule-denied files by accessing them through in-scope symbolic link aliases that resolve to denied paths.
