CVE-2026-73612

File Browser before v2.63.22 fails to validate access rules for descendants during recursive copy, rename, and delete operations, allowing authenticated users to bypass path-based access controls. Attackers can copy, rename, or delete denied files by operating on their allowed parent directory, defeating rule-based isolation for confidentiality and integrity.
