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 checksWork through these to decide whether this CVE applies to you.
-
Verify Melapress Login Security plugin is installedNavigate to WordPress admin > Plugins and look for 'Melapress Login Security' or check the plugins directory /wp-content/plugins/ for melapress-login-security folderAffected if The plugin is installed and active

-
Identify unserialize() data entry pointsSearch plugin files for 'unserialize' calls - look in PHP files within /wp-content/plugins/melapress-login-security/ for any $_GET, $_POST, or $_REQUEST parameters passed directly to unserialize()Affected if Any unserialize() call accepts input from request parameters without validation
-
Check user role access to vulnerable functionalityReview WordPress users > All Users and the plugin's role settings to determine which user roles can access Melapress Login Security settings and featuresAffected if Users with Subscriber, Contributor, or Author roles have access to plugin functionality
-
Audit access logs for PHP object injection attemptsReview web server access logs (Apache/nginx) and WordPress debug logs for patterns like 'unserialize' in query parameters or POST data to plugin endpointsAffected if Suspicious unserialize() injection attempts are found in logs
You are affected if Melapress Login Security plugin is installed with a version lower than 2.1.1 AND the plugin processes untrusted serialized data through user-controllable input.
