CVE-2025-32240 Overview
CVE-2025-32240 is a Missing Authorization vulnerability [CWE-862] affecting the wpvsingh Site Notify WordPress plugin. The flaw stems from incorrectly configured access control security levels, allowing unauthenticated attackers to reach plugin functionality that should be restricted to privileged users. All versions of Site Notify up to and including 1.0 are affected.
The vulnerability is exploitable 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 attackers can invoke protected plugin actions over the network, bypassing intended access control on WordPress sites running Site Notify 1.0 and earlier.
Affected Products
- wpvsingh Site Notify plugin for WordPress
- Site Notify versions n/a through 1.0
- WordPress installations with the vulnerable Site Notify plugin enabled

Technical Details for CVE-2025-32240
Vulnerability Analysis
The vulnerability is classified as Missing Authorization under [CWE-862]. The Site Notify plugin exposes one or more actions or endpoints without verifying that the requesting user has the appropriate role or capability. WordPress plugins typically enforce authorization using current_user_can() checks and nonce validation through check_admin_referer() or check_ajax_referer(). When these checks are absent or improperly implemented, any visitor can trigger privileged functionality.
According to the Patchstack WordPress Vulnerability Report, the issue is a broken access control weakness that affects Site Notify from unspecified early versions through 1.0. The Exploit Prediction Scoring System (EPSS) score is 0.294% at the 21.21 percentile, indicating low observed exploitation activity at this time.
Root Cause
The root cause is the absence of proper capability or role checks on plugin-exposed handlers. Requests routed to the affected functionality do not validate the caller's WordPress privileges. This gap allows unauthenticated actors to invoke actions intended for site administrators or editors.
Attack Vector
An attacker sends crafted HTTP requests directly to the vulnerable plugin endpoints on a target WordPress site. No credentials or user interaction are required. The attacker leverages the missing authorization check to modify plugin state or trigger notify actions, resulting in limited impact on data integrity and site availability.
No verified public exploit code is available for this vulnerability. See the Patchstack advisory for additional technical context.
Detection Methods for CVE-2025-32240
Indicators of Compromise
- Unexpected changes to Site Notify plugin settings or notification content on WordPress sites
- HTTP POST requests to wp-admin/admin-ajax.php or wp-admin/admin-post.php from unauthenticated sources targeting Site Notify actions
- Access log entries showing plugin endpoint requests without preceding authentication cookies
Detection Strategies
- Inventory WordPress installations and identify sites running the Site Notify plugin at version 1.0 or earlier
- Review web server access logs for requests to Site Notify handlers originating from anonymous sessions
- Correlate WordPress audit trail events with unauthenticated network activity targeting admin-ajax.php and admin-post.php
Monitoring Recommendations
- Enable WordPress activity logging to record configuration changes to installed plugins
- Forward WordPress and web server logs to a centralized analytics platform for retention and query
- Alert on anomalous request patterns to plugin endpoints outside of administrator sessions
How to Mitigate CVE-2025-32240
Immediate Actions Required
- Identify all WordPress sites running the Site Notify plugin and document the installed version
- Deactivate and remove Site Notify version 1.0 and earlier until a patched release is confirmed
- Restrict access to wp-admin/ endpoints using web application firewall rules or IP allowlisting where feasible
Patch Information
No vendor-supplied patched version is referenced in the available advisory data. Site owners should monitor the Patchstack advisory and the plugin's WordPress.org listing for an updated release. Until a fix is published, removing the plugin is the recommended remediation.
Workarounds
- Uninstall the Site Notify plugin entirely if it is not business-critical
- Deploy a WordPress-aware web application firewall to block unauthenticated requests to plugin action handlers
- Enforce IP-based restrictions on wp-admin/admin-ajax.php and wp-admin/admin-post.php to trusted networks where the workflow allows
