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.
-
Confirm Locker Content plugin installation and versionNavigate to WordPress Admin > Plugins and locate 'Locker Content', or check the plugin files in /wp-content/plugins/ for the version number in the main PHP file headerAffected if The plugin is installed and the version is 1.0.0 exactly, or if the version cannot be determined but the plugin is present
-
Verify the lockerco_submit_post AJAX endpoint existsCheck the plugin PHP files for the 'lockerco_submit_post' action hook registered via wp_ajax or wp_ajax_nopriv_, or attempt a POST request to /wp-admin/admin-ajax.php with action=lockerco_submit_postAffected if The endpoint is registered and responds to requests
-
Test unauthenticated access to the vulnerable endpointSend a crafted POST request to wp-admin/admin-ajax.php with action=lockerco_submit_post and parameters referencing protected content (e.g., post_id parameter) without authentication cookiesAffected if The endpoint returns protected content or responds with success status without requiring authentication
-
Check if content protection is enabled on any postsReview published posts/pages in WordPress admin for locker/metabox settings provided by the plugin, or inspect postmeta tables for locker-related custom fieldsAffected if Any posts have active content protection settings applied
A user is affected if the Locker Content plugin version 1.0.0 is installed with the lockerco_submit_post AJAX endpoint accessible to unauthenticated users and any protected content exists on the site.
