CVE-2024-12158
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedThe Popup – MailChimp, GetResponse and ActiveCampaign Intergrations plugin for WordPress is vulnerable to unauthorized loss of data due to a missing capability check on the 'upc_delete_db_data' AJAX action in all versions up to, and including, 3.2.6. This makes it possible for unauthenticated attackers to delete the DB data for the plugin.
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.

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 the Popup plugin is installedCheck your WordPress plugins directory (wp-content/plugins) for folders containing 'popup' and 'mailchimp' or 'popup-by-popup', or list installed plugins via WP-CLI: wp plugin list --status=active --format=csvAffected if The plugin appears in the active plugins list
-
Identify the installed plugin versionOpen the main plugin PHP file (usually popup.php, popup-by-popup.php, or similar in the plugin folder) and locate the 'Version:' header in the plugin comment block, or check the readme.txt fileAffected if The version number is lower than 3.2.7 (the fixed version)
-
Confirm the vulnerable AJAX endpoint existsSearch the plugin source code for 'upc_delete_db_data' to verify this AJAX action handler exists, or test access by sending a POST request to /wp-admin/admin-ajax.php with action=upc_delete_db_data (no authentication required)Affected if The AJAX action responds or the code contains the vulnerable handler without a capability check (look for 'current_user_can' or 'manage_options' in that function)
-
Check for database changes after potential exploitationReview your WordPress database tables, particularly any custom tables created by the plugin, for unexpected deletion or truncation; also check wp_posts/wp_postmeta for missing popup-related recordsAffected if Unexpected data loss is detected in plugin-related tables
You are affected if the Popup - MailChimp, GetResponse and ActiveCampaign Integrations plugin is installed with a version lower than 3.2.7 and the upc_delete_db_data AJAX action is accessible without authentication.

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.
dbcve · scopedUpdate the plugin to version 3.2.7 or later which includes the missing capability check. If immediate updating is not feasible, consider disabling the plugin or implementing WAF rules to block the vulnerable AJAX endpoint until patching is possible.
