Description
The Nexter Blocks – Gutenberg Blocks, Page Builder & AI Website Builder plugin for WordPress is vulnerable to Directory Traversal in all versions up to, and including, 5.0.0 via the 'plus_name' parameter. This makes it possible for authenticated attackers, with subscriber-level access and above, to delete arbitrary JS/CSS files on the server, which can lead to denial of service or destruction of critical plugin and theme assets.
