File Browser before v2.63.22 Authorization Bypass via Recursive Operations

Assigner: VulnCheck
Reserved: 13.08.2026 Published: 13.08.2026 Updated: 13.08.2026

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.
