CVE-2025-54162Network attack vector

Administrator file disclosure via path traversal

Published Feb 11, 2026 · Updated Feb 11, 2026

Path traversal in QNAP File Station 5 before 5.5.6.5068 allows remote authenticated users with administrator access to read unintended files. QNAP has not disclosed the affected endpoint, parameter, or exact pathname-validation failure, but the record identifies external path control and escape from an intended directory. Network access to the NAS application and an administrator account are required, and the reported consequence is limited to reading unexpected file contents or system data.
