This is due to missing file type validation in the upload_files function, which reads and applies an attacker-controlled extensions string from _super_elements post meta verbatim as the allowed MIME type map. This makes it possible for authenticated attackers, with Subscriber-level access and above, to upload files that may be executable, which makes remote code execution possible. The attack requires a preceding step: poisoning the _super_elements post meta via the super_save_form AJAX handler, which lacks a capability and nonce check but requires the attacker to be authenticated as at minimum a Subscriber-level user; the subsequent file upload via super_upload_files requires no authentication at all.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"twilight","depthScore":48,"depthScoreParts":{"impact":48.4,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
