CVE-2025-7827 Overview
CVE-2025-7827 affects the Ni WooCommerce Customer Product Report plugin for WordPress. The plugin fails to perform a capability check inside the ni_woocpr_action() function. Authenticated users with Subscriber-level access or higher can invoke this function and modify plugin settings. All versions through 1.2.4 are vulnerable. The weakness is classified as Missing Authorization [CWE-862].
Critical Impact
Any authenticated WordPress user, including low-privilege Subscribers, can modify plugin settings on affected sites.
Affected Products
- Ni WooCommerce Customer Product Report plugin for WordPress
- All versions up to and including 1.2.4
- WordPress sites running WooCommerce with this plugin installed

Technical Details for CVE-2025-7827
Vulnerability Analysis
The Ni WooCommerce Customer Product Report plugin exposes an AJAX-style handler named ni_woocpr_action(). This function updates plugin settings but omits a current_user_can() capability check. WordPress authenticates the request but never verifies that the caller holds administrative privileges. The result is a horizontal and vertical authorization gap. A Subscriber account, which is the lowest standard authenticated role, can alter configuration intended only for administrators.
The impact is limited to integrity of plugin configuration data. Confidentiality and availability remain unaffected based on the CVSS vector. However, modified plugin settings may redirect reporting behavior, change recipient addresses, or disable logging features that downstream workflows depend on.
Root Cause
The root cause is a missing authorization check inside the ni_woocpr_action() function. WordPress plugin developers must pair AJAX actions with current_user_can() validation and a verified wp_nonce token. This plugin registers the action for authenticated users but applies neither a role gate nor a capability gate before processing the settings update.
Attack Vector
Exploitation requires a valid WordPress account at Subscriber level or above. Many WordPress sites permit open user registration, which lowers this barrier substantially. The attacker sends a crafted request to the plugin's admin-ajax endpoint invoking ni_woocpr_action with the desired setting values. The server processes the update without rejecting the low-privilege caller. Refer to the Wordfence Vulnerability Report for technical analysis.

Stop Identity AttacksDetection Methods for CVE-2025-7827
Indicators of Compromise
- Unexpected changes to Ni WooCommerce Customer Product Report plugin settings in the WordPress database wp_options table
- POST requests to /wp-admin/admin-ajax.php with the action=ni_woocpr_action parameter from non-administrator sessions
- New or unexplained Subscriber-level user registrations preceding plugin configuration changes
Detection Strategies
- Audit WordPress access logs for admin-ajax.php requests containing ni_woocpr_action and correlate with the authenticated user role
- Compare current plugin settings against a known-good baseline to identify unauthorized modifications
- Enable WordPress activity logging plugins to capture settings changes with attributed user identity
Monitoring Recommendations
- Monitor the WordPress audit log for configuration changes performed by non-administrator accounts
- Alert on bulk registration of Subscriber accounts followed by AJAX activity targeting plugin actions
- Track outbound requests from the WordPress host that could indicate exfiltration via tampered report destinations
How to Mitigate CVE-2025-7827
Immediate Actions Required
- Deactivate the Ni WooCommerce Customer Product Report plugin until a patched version is installed
- Disable open user registration on WordPress sites where it is not required for business operations
- Review existing user accounts and remove Subscriber accounts that cannot be attributed to legitimate users
- Audit plugin settings and restore any values that have been modified without authorization
Patch Information
No fixed version is identified in the published advisory as of the last NVD update. Monitor the WordPress Plugin Page for releases above 1.2.4 and apply the update immediately upon availability.
Workarounds
- Remove the plugin entirely if the customer product reporting feature is not business-critical
- Restrict access to /wp-admin/admin-ajax.php using a web application firewall rule that blocks action=ni_woocpr_action requests from non-administrator sessions
- Enforce strong role separation and avoid granting Subscriber-level access to untrusted users
# Example WAF rule concept for ModSecurity to block the vulnerable action
# from authenticated non-admin sessions. Adjust the admin cookie match
# pattern to your environment before deploying.
