## Technical details

The vulnerability is classified as an arbitrary file deletion (CWE-73) resulting from insufficient file path validation within the 'become-dealer' logo upload flow. Specifically, the plugin's profile update handler allows authenticated users to provide an arbitrary filesystem path. An attacker with at least subscriber-level privileges can exploit this by sending a crafted request to delete sensitive files on the server, such as wp-config.php, which could lead to site takeover or denial of service. The issue affects all versions up to and including 1.4.107; a fix was introduced in changeset 3505874.
