Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Verify wpForo Forum plugin is installedLog into WordPress admin dashboard, navigate to Plugins > Installed Plugins, and look for 'wpForo Forum' or 'WpForo' in the list of active pluginsAffected if wpForo Forum appears in the plugins list and is activated
-
Check installed version numberIn WordPress admin, go to Plugins > Installed Plugins, find wpForo Forum, and read the version number displayed below the plugin name. Alternatively, check /wp-content/plugins/wpforo/functions.php or the main plugin PHP file for 'Version:' in the file headerAffected if Version displayed is 2.0.9 or lower (any version <= 2.0.9)
-
Confirm vulnerable state-changing operations existThe vulnerability affects any wpForo form submission or AJAX action that modifies data (forum posts, user settings, membership changes). Check if the plugin has any active forms or AJAX endpoints by inspecting page source of wpForo pages and looking for form elements with action attributes pointing to wp-admin/admin-ajax.php or forum submission URLsAffected if wpForo is active and serving pages with forms or AJAX functionality without CSRF token validation (nonce fields)
-
Inspect form submissions for missing nonceView source of any wpForo page with a form (new topic, reply, user profile). Check if forms contain an input field with name containing 'nonce' or '_wpnonce'. If these fields are missing from state-changing forms, the vulnerability is presentAffected if Forms on wpForo pages lack nonce verification fields
A user is affected if wpForo Forum plugin is installed and active with version 2.0.9 or lower, and the plugin handles any user-submitted content or settings without CSRF token validation.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement anti-CSRF tokens (nonce verification) on all state-changing form submissions and AJAX actions within the plugin, and add proper referer/Origin header validation on the server side.
