\n# \ud83d\udc1a CVE-2025-32682 – Arbitrary File Upload in MapSVG Lite <= 8.5.34\n\n ## \ud83d\udccc Plugin Details
– **Name:** MapSVG Lite
– **Affected Version:** <= 8.5.34
– **Vulnerability Type:** Arbitrary File Upload
– **CVE ID:** CVE-2025-32682
– **Published Date:** 15 April, 2025
– **CVSS Score:** 9.9 (Critical)<\/p>\n
—<\/p>\n
## \ud83d\udca5 Vulnerability Summary
The `MapSVG Lite` plugin for WordPress does not validate file types when uploading SVG files via its REST API endpoint:<\/p>\n
“`
\/wp-json\/mapsvg\/v1\/svgfile
“`<\/p>\n
This allows an authenticated attacker (Subscriber+) to upload arbitrary PHP files disguised as SVG, resulting in remote code execution (RCE).<\/p>\n
—<\/p>\n
## \ud83d\udcce Proof of Concept (POC) – Raw HTTP Request

### \ud83d\udd0d Vulnerable Code Snippet
The following vulnerable code snippet from the `mapsvg-lite-interactive-vector-maps.php` file highlights the issue:
“`php
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);
}
“`
– \u274c **No filetype check**
– \u274c **No extension validation**
– \u274c **No sanitization of file contents**<\/p>\n
This function is directly mapped to the REST endpoint `\/wp-json\/mapsvg\/v1\/svgfile`.<\/p>\n
—<\/p>\n
## \ud83e\udde0 Exploitation Requirements
– \u2705 Requires authentication (Subscriber+)
– \ud83d\uded1 No filetype or content validation<\/p>\n
—<\/p>\n
