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.

The plugin deserializes untrusted user input without proper validation, allowing authenticated attackers (or unauthenticated depending on plugin configuration) to inject malicious PHP objects that could lead to remote code execution.

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 the plugin is installedIn WordPress admin, go to Plugins and look for 'Phoenixheart AJAX Random Posts' or 'AJAX Random Posts' in the installed plugins listAffected if The plugin appears in the WordPress plugins list, regardless of activation status
-
Identify the installed versionClick on the plugin name in the Plugins list to view version details, or open /wp-content/plugins/ajax-random-posts/ajax-random-posts.php and check the Version header commentAffected if The version number matches or is older than any vulnerable version release of this plugin
-
Check if the ajax-random-posts function is accessibleTest the AJAX endpoint by making a request to /wp-admin/admin-ajax.php?action=ajax_random_posts (or the endpoint defined by the plugin) using curl or a browserAffected if The endpoint responds and accepts user-supplied input
-
Determine if unauthenticated access is allowedReview the plugin settings page in WordPress admin for any options controlling access level, or examine the plugin code for capability checks around the ajax-random-posts actionAffected if The plugin permits unauthenticated (guest) users to trigger the vulnerable function, or no capability check is present in the code
-
Look for signs of exploitation attemptsCheck WordPress debug logs, server access logs, and security logs for serialized data (O: or C: patterns) in requests to the ajax-random-posts endpointAffected if Any log entries show serialized PHP objects or unusual payloads being sent to the ajax-random-posts endpoint
Your environment is affected if the AJAX Random Posts plugin is installed and the ajax-random-posts function is accessible to attackers, regardless of authentication level.
