CVE-2025-46458 Overview
CVE-2025-46458 is a Cross-Site Request Forgery (CSRF) vulnerability in the occupancyplan WordPress plugin that chains into SQL Injection. The flaw affects all versions of the plugin up to and including 1.0.3.0. An attacker can craft a malicious page that, when visited by an authenticated WordPress user, triggers state-changing requests that pass attacker-controlled SQL into the plugin's database queries. The issue is classified under CWE-352 and tracked by Patchstack.
Critical Impact
A successful attack can disclose database contents and degrade site availability when an authenticated user is lured into visiting an attacker-controlled page.
Affected Products
- WordPress occupancyplan plugin versions up to and including 1.0.3.0
- WordPress sites running the vulnerable plugin with authenticated administrative users
- Any deployment where browser sessions for the WordPress admin remain active during browsing

Technical Details for CVE-2025-46458
Vulnerability Analysis
The vulnerability combines two distinct weaknesses in the occupancyplan plugin. The plugin exposes one or more request handlers that change server state without verifying a WordPress nonce or other anti-CSRF token. Those same handlers concatenate request parameters into SQL statements without parameterized queries or proper escaping. An attacker hosts a page containing a forged form or fetch request targeting the vulnerable endpoint. When a logged-in WordPress user with sufficient privileges visits the page, the browser submits the request with valid session cookies. The plugin then executes the attacker-supplied SQL within the victim's session context.
The scope-changed impact reflects that the database compromise extends beyond the plugin into the broader WordPress installation. Because user interaction is required, the attack relies on social engineering or watering-hole techniques rather than direct network exploitation.
Root Cause
The root cause is missing CSRF protection on database-bound request handlers, compounded by unsanitized input flowing into SQL statements. The plugin does not validate WordPress nonces using wp_verify_nonce() or check_admin_referer() and does not use $wpdb->prepare() for query construction.
Attack Vector
Exploitation is network-based and requires user interaction. The attacker delivers a malicious link or embedded resource to an authenticated WordPress user, typically an administrator. The victim's browser issues a cross-origin request to the vulnerable plugin endpoint carrying the attacker's SQL payload. Refer to the Patchstack advisory for endpoint specifics.
Detection Methods for CVE-2025-46458
Indicators of Compromise
- Unexpected POST or GET requests to occupancyplan plugin endpoints with SQL metacharacters such as UNION, SELECT, --, or ' OR .
- HTTP Referer headers on plugin admin actions originating from external, non-WordPress domains.
- Anomalous rows or modifications in tables associated with the plugin.
- WordPress audit logs showing admin-level actions immediately after the user visited an external site.
Detection Strategies
- Inspect web server access logs for requests to occupancyplan endpoints lacking valid _wpnonce parameters.
- Deploy a Web Application Firewall (WAF) rule set that flags SQL injection patterns targeting WordPress plugin paths.
- Enable MySQL query logging during incident response to capture injected statements referencing plugin tables.
Monitoring Recommendations
- Track outbound database errors returned to plugin endpoints, which often indicate injection probing.
- Alert on cross-origin form submissions to /wp-admin/admin-ajax.php or /wp-admin/admin-post.php with action= parameters tied to the plugin.
- Correlate authenticated session activity with browsing telemetry to identify CSRF delivery vectors.
How to Mitigate CVE-2025-46458
Immediate Actions Required
- Disable or remove the occupancyplan plugin until a patched release is confirmed.
- Force-rotate WordPress administrator passwords and invalidate active sessions using wp_destroy_all_sessions().
- Review the WordPress database for unauthorized modifications, paying close attention to wp_users and wp_options.
- Restrict access to /wp-admin/ by IP allowlist where operationally feasible.
Patch Information
No fixed version is identified in the available NVD or Patchstack data at the time of publication. The vulnerability affects all releases through 1.0.3.0. Monitor the Patchstack advisory for vendor remediation updates.
Workarounds
- Add WAF signatures that block SQL injection payloads on plugin endpoints.
- Require administrators to use isolated browser profiles or sessions when managing WordPress.
- Enforce SameSite=Strict cookie policies on WordPress authentication cookies to reduce CSRF exposure.
- Apply least-privilege roles so that fewer users hold capabilities the plugin checks against.
# Configuration example: disable the vulnerable plugin via WP-CLI
wp plugin deactivate occupancyplan
wp plugin delete occupancyplan
