dbcve checksWork through these to decide whether this CVE applies to you.
-
Verify Contact Form 7 Live Preview plugin is installedCheck the WordPress plugins directory for the contact-form-7-live-preview folder, or look for it in WP Admin under Plugins > Installed PluginsAffected if The plugin is present and active in the WordPress installation

-
Test unauthenticated access to preview functionalityLog out of WordPress completely, then attempt to access the live preview URL endpoint (commonly /?cf7lp_preview=1 or similar preview routes used by the plugin) using a browser or curlAffected if The preview renders and displays form content without requiring login or administrator privileges
-
Verify authorization checks in plugin codeExamine the plugin PHP files for capability verification functions such as current_user_can('manage_options') or similar authorization checks before preview rendering code executesAffected if No capability or authorization verification is performed before displaying preview data to users
