Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
The wcfm_ajax_controller AJAX action of the WCFM Marketplace WordPress plugin before 3.4.12, available to unauthenticated and authenticated user, does not properly sanitise multiple parameters before using them in SQL statements, leading to SQL injections

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis
How this class of weakness works · CWE-89

User input is woven into a database query, letting an attacker rewrite the query's logic. From there they can read, alter, or destroy data — frequently the entire database. The reliable fix is parameterised queries (prepared statements), so input is always treated as data and never as SQL.

WCFM Marketplace plugin version 3.4.12 or later

  3. Locate WCFM Marketplace (Frontend Manager For Woocommerce) in the plugin list
  4. Click Update Now to install the latest version, or manually upload version 3.4.12 or later from the WordPress plugin repository
  5. Verify the plugin version shows 3.4.12 or higher under the plugin name
  6. Test critical marketplace functionality (vendor registration, product listings, orders) to ensure the update did not break existing features
Caveat Standard WordPress plugin update - test in staging environment first if available, as custom themes or other plugins may have compatibility considerations
