 "title": "Groundhogg <= 4.9.3 - Authenticated (Sales Representative+) Arbitrary File Deletion via Contact File Copying",
 "description": "The Groundhogg plugin for WordPress is vulnerable to arbitrary file deletion via the contact file copy feature ('files' and 'copy_file' contact fields used by the REST API and contact imports) in all versions up to, and including, 4.9.3, due to insufficient validation of the source file path in the File_Box::copy_file() function. When a local path outside the uploads directory was supplied, the sideload was rejected and the plugin then deleted the supplied path. This makes it possible for authenticated attackers, with Sales Representative-level access and above, to delete arbitrary files on the server, such as wp-config.php, which can make remote code execution possible.",
