Is WCFM Marketplace safe? Known vulnerabilities and latest version

The WCFM Marketplace – Multivendor Marketplace for WooCommerce plugin for WordPress is vulnerable to generic SQL Injection via the 'wcfmmp_user_location_lng' parameter in all versions up to, and including, 3.8.2 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

Contributor Cross Site Scripting (XSS) in WCFM Marketplace <= 3.8.2 versions.

Unauthenticated SQL Injection in WCFM Marketplace <= 3.8.1 versions.

The WCFM Marketplace WordPress plugin before 3.8.2 does not correctly verify that the person requesting a refund owns the order, allowing unauthenticated users to create refund requests against any guest checkout order on the site.

The WCFM Marketplace WordPress plugin before 3.8.1 does not verify that a marketplace vendor owns a review before allowing it to be unapproved or deleted, allowing any vendor to modify or permanently delete reviews belonging to other vendors' stores.

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.
