CVE-2026-12126 Detail

Description

The WCFM Marketplace – Multivendor Marketplace for WooCommerce plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Attachment 'post_title' in all versions up to, and including, 3.7.3 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Vendor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. An attacker can plant the payload by uploading a media attachment with a crafted title via the WordPress REST API (/wp-json/wp/v2/media), without ever invoking the AJAX endpoint themselves, as the unescaped title is later emitted inside DataTables JSON and inserted as innerHTML upon any privileged user loading the media dashboard.
