CVE-2024-10672: Multiple Page Generator Plugin – MPG <= 4.0.2 - Authenticated (Editor+) Directory Traversal to Limited File Deletion

The Multiple Page Generator Plugin – MPG plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the mpg_upsert_project_source_block() function in all versions up to, and including, 4.0.2. This makes it possible for authenticated attackers, with editor-level access and above, to delete limited files on the server.
