Administrator-only file disclosure via path traversal
Published Oct 3, 2025 · Updated Oct 3, 2025
Path traversal in QNAP QTS 5.2.x and QuTS hero h5.2.x allows remote authenticated users with administrator access to read unexpected files. QNAP has not published the affected component or the operation that fails to constrain attacker-controlled path input. Administrator access to the NAS management surface is required, and the reported consequence is file and system-data disclosure without modification or service interruption.
