Authenticated file read via unrestricted thumbnail path
Published Jul 11, 2026 · Updated Jul 11, 2026
Path traversal in WebFactory Ltd Under Construction Page Pro 5.76 and earlier allows remote authenticated users to read server files. The template_thumbnail handler accepts an arbitrary local path and copies the referenced file into a publicly reachable uploads file without restricting the path. Subscriber-level access is sufficient, and exposure is limited to files readable by the WordPress server process.
