CVE-2025-13516
The SureMail plugin for WordPress contains a flaw in its attachment handling mechanism, allowing unauthenticated users to upload malicious files with potentially hazardous types into a publicly accessible directory. This occurs due to insufficient validation of file extensions and content types within the save_file() function in inc/emails/handler/uploads.php.
