CVE-2025-30916 Overview
CVE-2025-30916 is a Missing Authorization vulnerability [CWE-862] in the Enitute Technology Residential Address Detection plugin for WordPress. The flaw affects all plugin versions up to and including 2.5.4. Attackers can exploit incorrectly configured access control security levels to interact with plugin functionality that should be restricted. The vulnerability is exploitable remotely over the network without authentication or user interaction. Successful exploitation can lead to limited integrity and availability impact on affected WordPress sites running the plugin.
Critical Impact
Unauthenticated network attackers can bypass access controls in the Residential Address Detection plugin, enabling misuse of restricted plugin operations on WordPress sites through versions <= 2.5.4.
Affected Products
- Enitute Technology Residential Address Detection plugin for WordPress
- All versions from initial release through 2.5.4
- WordPress sites with the residential-address-detection plugin installed and active

Technical Details for CVE-2025-30916
Vulnerability Analysis
The vulnerability stems from missing authorization checks within the Residential Address Detection plugin. The plugin exposes functionality without verifying whether the requesting user holds the required capabilities or role. This class of flaw, categorized under [CWE-862] Missing Authorization, occurs when code paths that perform sensitive operations lack proper permission validation before execution.
The attack surface is reachable over the network. An unauthenticated attacker can send crafted HTTP requests to plugin endpoints and trigger actions intended for privileged users. Because the plugin performs address validation and configuration operations, the impact is scoped to limited integrity and availability rather than direct data disclosure.
Root Cause
The root cause is an incorrectly configured access control security level in the plugin's request handlers. Endpoints that should validate user capabilities using WordPress functions such as current_user_can() or nonce verification through check_ajax_referer() either omit these checks or apply them inconsistently. This allows external callers to reach restricted logic paths directly.
Attack Vector
Exploitation requires only network access to a vulnerable WordPress installation. An attacker crafts HTTP requests targeting the plugin's exposed action handlers, typically through the WordPress AJAX endpoint at /wp-admin/admin-ajax.php or REST API routes registered by the plugin. Because no authentication or user interaction is required, automated scanners can identify and exploit vulnerable sites at scale. See the PatchStack Vulnerability Report for additional technical context.
Detection Methods for CVE-2025-30916
Indicators of Compromise
- Unauthenticated POST or GET requests to /wp-admin/admin-ajax.php referencing residential-address-detection plugin actions.
- Requests to plugin-registered REST endpoints originating from unauthenticated sessions or unfamiliar IP addresses.
- Unexpected changes to plugin configuration or address validation results in WordPress logs.
Detection Strategies
- Inventory WordPress installations and identify sites running the residential-address-detection plugin at version 2.5.4 or earlier.
- Review web server access logs for anomalous request patterns targeting plugin action handlers without valid session cookies.
- Correlate WordPress audit logs with authentication events to identify actions performed without an associated logged-in user.
Monitoring Recommendations
- Enable verbose logging on the WordPress instance and forward logs to a centralized SIEM for correlation.
- Deploy a Web Application Firewall (WAF) with rules that inspect requests to the vulnerable plugin's endpoints.
- Monitor for spikes in traffic to admin-ajax.php with the plugin's action parameters from external IPs.
How to Mitigate CVE-2025-30916
Immediate Actions Required
- Identify all WordPress sites running the Residential Address Detection plugin at version <= 2.5.4.
- Update the plugin to a fixed version once released by the vendor, or deactivate and remove the plugin if no patch is available.
- Restrict administrative access and enforce strong authentication on WordPress admin accounts.
Patch Information
Refer to the PatchStack Vulnerability Report for the current patch status. Administrators should upgrade to any release later than 2.5.4 provided by Enitute Technology. Verify plugin integrity after upgrading by comparing installed files against the vendor-supplied distribution.
Workarounds
- Deactivate the residential-address-detection plugin until a fixed version is confirmed available.
- Add WAF rules that block unauthenticated requests to the plugin's AJAX and REST endpoints.
- Restrict access to /wp-admin/admin-ajax.php from untrusted networks where feasible using IP allow-listing at the reverse proxy.
