Atarim <= 5.1.1 - Authenticated (Author+) Arbitrary File Deletion via '_wp_attached_file' Meta
The Atarim – AI Agency for WordPress: Edit Pages, Fix Code, Update Plugins, SEO & Client Feedback plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the AVCF_Abilities_Media::register (replace-media-file execute_callback) function in all versions up to, and including, 5.1.1. This makes it possible for authenticated attackers, with author-level access and above, to delete arbitrary files on the server, which can easily lead to remote code execution when the right file is deleted (such as wp-config.php). This is exploitable by first using the atarim/update-post-field ability to overwrite the _wp_attached_file meta of an attacker-owned attachment with a directory-traversal path, then invoking atarim/replace-media-file to cause get_attached_file() to resolve and unlink the targeted file.
