CVE-2025-46498 Overview
CVE-2025-46498 is a Cross-Site Request Forgery (CSRF) vulnerability affecting the Zalo Official Live Chat WordPress plugin developed by nghialuu. The flaw impacts all plugin versions up to and including 1.0.0. An attacker can craft a malicious web page that, when visited by an authenticated administrator, triggers unauthorized state-changing actions in the WordPress site. The weakness is classified under CWE-352 and requires user interaction to succeed. The vulnerability was disclosed through Patchstack's WordPress vulnerability database.
Critical Impact
An attacker can trick an authenticated administrator into submitting forged requests that modify plugin settings without consent, resulting in limited integrity and availability impact.
Affected Products
- nghialuu Zalo Official Live Chat plugin for WordPress
- All versions from n/a through 1.0.0
- WordPress sites with the zalo-official-live-chat plugin installed and activated

Technical Details for CVE-2025-46498
Vulnerability Analysis
The Zalo Official Live Chat plugin fails to implement adequate anti-CSRF protections on one or more state-changing endpoints. WordPress provides the wp_nonce_field() and check_admin_referer() primitives to validate that requests originate from authorized sessions. When these validation checks are missing or improperly implemented, an attacker can forge requests that ride on an administrator's authenticated session cookies. The exploit path requires an authenticated user, typically an administrator, to visit an attacker-controlled page while logged in to WordPress. The browser automatically attaches session cookies to the forged request, causing the plugin to accept and process the attacker's payload.
Root Cause
The root cause is missing or insufficient CSRF token validation on plugin request handlers. Without a nonce check tied to the current user session, the plugin cannot distinguish legitimate administrator actions from forged submissions triggered by cross-origin requests.
Attack Vector
Exploitation occurs over the network and requires user interaction. An attacker hosts a malicious HTML page containing a hidden form or JavaScript that auto-submits a request to the vulnerable WordPress endpoint. When an authenticated administrator visits the page, the browser sends the request with valid session cookies, and the plugin executes the requested action. Technical details are documented in the Patchstack WordPress Vulnerability Report.
Detection Methods for CVE-2025-46498
Indicators of Compromise
- Unexpected changes to Zalo Official Live Chat plugin settings within the WordPress admin dashboard
- Web server access logs showing POST requests to plugin endpoints with Referer headers pointing to external domains
- Administrator sessions initiating plugin configuration changes shortly after visiting external websites
Detection Strategies
- Inspect WordPress audit logs for plugin option updates that lack a corresponding admin UI interaction
- Monitor HTTP request patterns for cross-origin POST requests targeting /wp-admin/admin.php or plugin AJAX handlers without valid nonce parameters
- Deploy a Web Application Firewall (WAF) rule to flag requests to plugin endpoints missing _wpnonce values
Monitoring Recommendations
- Enable WordPress activity logging to capture administrator-initiated configuration changes with timestamps and source IP addresses
- Correlate browser referrer data with administrator sessions to identify suspicious cross-origin activity
- Alert on plugin setting modifications outside of expected maintenance windows
How to Mitigate CVE-2025-46498
Immediate Actions Required
- Deactivate the zalo-official-live-chat plugin until a patched version is available from the vendor
- Restrict WordPress administrator accounts to dedicated browsing profiles that avoid arbitrary web browsing
- Enforce strong session management by requiring administrators to log out after configuration tasks
Patch Information
At the time of publication, no fixed version has been listed in the NVD entry. Site owners should monitor the Patchstack advisory and the plugin's WordPress.org page for an updated release that adds nonce validation to affected endpoints.
Workarounds
- Remove or disable the plugin if it is not essential to site operations
- Configure a WAF to require valid WordPress nonce parameters on plugin request paths
- Apply the principle of least privilege by limiting the number of accounts with the manage_options capability
