CVE-2026-77006

WebTotem Backups < 1.1.0 - Subscriber+ Arbitrary File Deletion via Path Traversal

The WebTotem Backups WordPress plugin through 1.0.1 does not validate a user-supplied file path, does not check the capability of the user making the request, and discards the result of its own CSRF check, allowing any authenticated user, such as a subscriber, to delete arbitrary files on the server, which can lead to a site takeover.
