CVE-2025-12370 Overview
The Takeads plugin for WordPress contains an authorization bypass vulnerability affecting all versions up to and including 1.0.13. The plugin fails to verify that a user is authorized to perform specific actions before executing them. Authenticated attackers with subscriber-level access or higher can exploit this flaw to delete the plugin's configuration options. The weakness is classified under CWE-862: Missing Authorization and stems from missing capability checks in the plugin's AJAX handlers.
Critical Impact
Authenticated users with minimal privileges can delete Takeads plugin configuration, disrupting site monetization functionality and requiring administrative restoration.
Affected Products
- Takeads (formerly Monetize Link) plugin for WordPress
- All plugin versions up to and including 1.0.13
- WordPress sites with subscriber registration enabled

Technical Details for CVE-2025-12370
Vulnerability Analysis
The Takeads plugin registers AJAX endpoints in src/MLP_Ajax.php that modify plugin configuration state. These endpoints omit proper capability checks required by the WordPress security model. Any authenticated user, including those with the subscriber role, can invoke the deletion action and remove stored plugin options.
WordPress plugins must validate two conditions before performing privileged actions. The plugin must verify the request originates from an authorized user via current_user_can() and confirm request authenticity through nonce validation. This plugin performs neither check consistently on state-changing operations.
The impact is limited to integrity of plugin configuration data. Confidentiality and availability of the wider WordPress installation remain unaffected. However, deleted configuration can break monetization workflows and require manual administrator intervention.
Root Cause
The root cause is missing authorization logic in the plugin's AJAX action handlers. The developer relied on authentication alone rather than verifying the acting user holds the appropriate WordPress capability such as manage_options. Refer to the WordPress plugin source at MLP_Ajax.php for the affected handler code.
Attack Vector
Exploitation requires network access to the target WordPress site and valid credentials for any account, including a subscriber account created through open registration. The attacker sends a crafted admin-ajax.php request invoking the vulnerable action. The server processes the request and deletes the plugin's configuration options without validating the caller's role. No user interaction from an administrator is required.
See the Wordfence Vulnerability Report for additional technical details.
Detection Methods for CVE-2025-12370
Indicators of Compromise
- Unexpected resets or missing entries in Takeads plugin settings within wp_options
- POST requests to /wp-admin/admin-ajax.php originating from subscriber accounts targeting Takeads AJAX actions
- Administrator reports of monetization links no longer rendering after configuration loss
- New subscriber accounts registered shortly before configuration changes
Detection Strategies
- Review WordPress audit logs for AJAX actions invoked by low-privilege users referencing the monetize-link or Takeads action names
- Monitor wp_options table changes for deletions of Takeads-related option keys
- Compare current plugin configuration against known-good backups to detect unauthorized removal
Monitoring Recommendations
- Deploy a WordPress activity logging plugin to record option changes and AJAX invocations
- Alert on any state-changing AJAX request issued by users with the subscriber role
- Track failed and successful authentication events tied to newly created accounts
How to Mitigate CVE-2025-12370
Immediate Actions Required
- Update the Takeads plugin to a version later than 1.0.13 once released by the vendor
- If no patched version is available, deactivate the Takeads plugin until a fix is published
- Disable open user registration or restrict the default role for new users on public-facing WordPress sites
- Audit existing subscriber accounts and remove those that are unrecognized or inactive
Patch Information
At the time of publication, the vendor advisory referenced by Wordfence tracks fix availability. Administrators should monitor the plugin's WordPress.org page and apply the first release above version 1.0.13 that addresses [CWE-862].
Workarounds
- Restrict access to /wp-admin/admin-ajax.php from unauthenticated and low-privileged users via a Web Application Firewall (WAF) rule targeting Takeads action names
- Set users_can_register to false in WordPress General Settings to prevent creation of new subscriber accounts
- Back up the wp_options table on a regular schedule to enable rapid restoration of plugin configuration
# Disable user self-registration via WP-CLI
wp option update users_can_register 0
# Deactivate the vulnerable plugin until patched
wp plugin deactivate monetize-link
# Back up wp_options for recovery
wp db export --tables=$(wp db prefix)options backup-options.sql
