Vulnerability Title
Groundhogg <= 4.9.3 - Authenticated (Sales Representative+) Arbitrary File Deletion via CSV Import 'copy_file' Field Mapping
Source: CVE Program / CVE List V5
Vulnerability Description
The Groundhogg — CRM, Newsletters, and Marketing Automation plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the copy_file function in all versions up to, and including, 4.9.3 This makes it possible for authenticated attackers, with Sales Representative-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 any user holding the plugin-defined import_contacts capability, which is granted by default to the plugin's custom Sales Representative role.
