Summary
The WCFM Marketplace plugin for WordPress is vulnerable to Stored Cross-Site Scripting in versions up to 3.7.3 due to insufficient input sanitization and output escaping of the 'post_title' field. Authenticated attackers with Vendor-level access or higher can inject arbitrary web scripts that execute when users access affected pages.
Risk Assessment
Attackers can hijack admin sessions, steal sensitive data, or spread malware within the WordPress environment. The vulnerability also allows privilege escalation through script execution in the victim's browser context.
Recommendation
Immediately update the WCFM Marketplace plugin to the latest patched version. Additionally, restrict access to the WordPress REST API for unauthorized users.

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.
