MaxiBlocks Builder plugin for WordPress up to version 2.1.8 allows authenticated attackers with Author-level access to delete arbitrary files in the wp-content/uploads directory via the 'maxi_remove_custom_image_size' AJAX action due to insufficient file ownership validation. This enables deletion of media uploaded by other users and administrators without proper authorization checks, violating file integrity despite the CVSS 5.3 score reflecting limited direct impact.
