Sensitive file disclosure via path traversal
Published May 22, 2026 · Updated May 22, 2026
Path traversal in Ubiquiti UniFi OS devices before applicable fixed releases allows remote authenticated users to read system files. Ubiquiti has not disclosed the affected endpoint or the path-validation operation that permits traversal outside the intended directory. Low-privileged network access is required, and the disclosed consequence is limited to obtaining sensitive information from accessible underlying-system files.
