CVE-2025-66148 Overview
CVE-2025-66148 is a missing authorization vulnerability in the merkulove Conformer for Elementor WordPress plugin (conformer-elementor). The flaw affects all versions from initial release through 1.0.7 and stems from incorrectly configured access control security levels [CWE-862]. An authenticated attacker with low privileges can exploit the plugin to perform actions that should be restricted to higher-privileged roles. The vulnerability impacts integrity and availability of the affected site.
Critical Impact
Authenticated users with minimal privileges can invoke restricted plugin functionality due to missing authorization checks in Conformer for Elementor versions through 1.0.7.
Affected Products
- merkulove Conformer for Elementor (conformer-elementor) plugin
- All versions from initial release through 1.0.7
- WordPress sites running the vulnerable plugin

Technical Details for CVE-2025-66148
Vulnerability Analysis
The vulnerability is a broken access control issue classified under [CWE-862] Missing Authorization. The Conformer for Elementor plugin exposes functionality without verifying that the calling user holds the required capability or role. Attackers reach the vulnerable code paths over the network with low privileges and without user interaction. Exploitation can modify plugin-controlled state and disrupt normal site behavior, producing limited impact on integrity and availability. Confidentiality is not affected based on the published scoring.
Root Cause
The plugin registers action handlers or endpoints that omit capability checks such as current_user_can() and, where applicable, nonce verification via check_admin_referer() or wp_verify_nonce(). Because access control decisions are not enforced server-side, any authenticated session can invoke these entry points regardless of the user's assigned role.
Attack Vector
An attacker authenticates to the WordPress site with any low-privilege account, such as Subscriber or Contributor. The attacker then sends HTTP requests to the plugin's exposed action handlers or admin-ajax endpoints. Because the plugin does not enforce authorization, the requests execute successfully and alter plugin configuration or state. Refer to the Patchstack Vulnerability Report for technical details.
Detection Methods for CVE-2025-66148
Indicators of Compromise
- Unexpected changes to Conformer for Elementor plugin settings or Elementor-managed content authored by low-privilege accounts.
- HTTP POST requests to wp-admin/admin-ajax.php or plugin action endpoints originating from Subscriber-level sessions.
- New or modified WordPress options and postmeta rows tied to the conformer-elementor plugin outside of administrator activity windows.
Detection Strategies
- Inventory WordPress installations and identify sites running conformer-elementor version 1.0.7 or earlier.
- Review web server access logs for authenticated requests to plugin-specific action names correlated with non-admin user IDs.
- Compare current plugin settings against a known-good baseline to identify unauthorized modifications.
Monitoring Recommendations
- Enable WordPress audit logging to capture option changes, user role changes, and plugin configuration updates.
- Alert on repeated admin-ajax.php requests from low-privilege accounts targeting the same action parameter.
- Monitor for new administrator accounts or capability grants that follow suspicious plugin-related activity.
How to Mitigate CVE-2025-66148
Immediate Actions Required
- Update Conformer for Elementor to a version later than 1.0.7 once the vendor publishes a patched release.
- If no patched version is available, deactivate and remove the conformer-elementor plugin from all affected WordPress sites.
- Audit low-privilege user accounts and remove any that are unused or unrecognized.
Patch Information
At the time of NVD publication, the advisory covers Conformer for Elementor versions through 1.0.7. Consult the Patchstack Vulnerability Report for the current fixed version and vendor guidance.
Workarounds
- Restrict access to wp-admin/admin-ajax.php and plugin endpoints using a web application firewall until the plugin is patched or removed.
- Disable open user registration and enforce strong authentication to reduce the pool of low-privilege accounts available to attackers.
- Apply the principle of least privilege by reviewing custom roles and removing unnecessary capabilities.
