Advisory
Source description from Wordfence Intelligence, credited to Teerachai Somprasong.
The MaxiBlocks Builder plugin for WordPress is vulnerable to arbitrary media file deletion due to insufficient file ownership validation on the 'maxi_remove_custom_image_size' AJAX action in all versions up to, and including, 2.1.8. This makes it possible for authenticated attackers, with Author-level access and above, to delete arbitrary files in the wp-content/uploads directory, including files uploaded by other users and administrators.
