CVE-2025-31034 Overview
CVE-2025-31034 is a Cross-Site Request Forgery (CSRF) vulnerability affecting the AboZain Albanna Customize Login Page WordPress plugin. The flaw impacts all plugin versions up to and including 1.1. An attacker can craft a malicious web page or link that, when visited by an authenticated administrator, triggers unauthorized settings changes on the target WordPress site. The vulnerability is classified under CWE-352: Cross-Site Request Forgery. Exploitation requires user interaction but no privileges on the attacker's side.
Critical Impact
Attackers can modify plugin settings on vulnerable WordPress sites by tricking an authenticated administrator into visiting a malicious page.
Affected Products
- AboZain Albanna Customize Login Page plugin for WordPress
- All versions from n/a through 1.1
- WordPress installations with the affected plugin activated

Technical Details for CVE-2025-31034
Vulnerability Analysis
The vulnerability stems from missing or improperly implemented anti-CSRF protections in the plugin's settings handlers. WordPress provides nonce mechanisms via wp_nonce_field() and check_admin_referer() to validate the origin of state-changing requests. The Customize Login Page plugin fails to enforce these checks on requests that modify plugin configuration. As a result, the server accepts forged requests as legitimate when accompanied by valid session cookies.
The attack requires user interaction, meaning a logged-in administrator must load attacker-controlled content. Confidentiality is not directly impacted, but integrity of plugin settings can be altered without consent.
Root Cause
The root cause is the absence of nonce validation on POST handlers responsible for updating plugin options. The plugin trusts the presence of an authenticated session cookie without verifying that the request originated from a legitimate admin form submission. This design pattern violates the CSRF protections mandated by the WordPress plugin security guidelines.
Attack Vector
An attacker hosts a malicious HTML page containing an auto-submitting form or image tag that issues a POST request to the vulnerable plugin's settings endpoint. When a WordPress administrator visits this page while logged in, the browser automatically attaches the session cookie. The server processes the request and applies the attacker-specified settings. No credentials or elevated privileges are required on the attacker's side. Full technical detail is available in the Patchstack Vulnerability Report.
Detection Methods for CVE-2025-31034
Indicators of Compromise
- Unexpected changes to Customize Login Page plugin settings without administrator action
- POST requests to plugin settings endpoints originating from external Referer headers
- WordPress admin activity from unusual IP addresses correlated with settings modifications
- Modifications to the login page appearance or behavior outside of change windows
Detection Strategies
- Review web server access logs for POST requests to WordPress admin endpoints lacking a same-origin Referer header
- Enable WordPress audit logging plugins to track option changes and identify unauthorized modifications
- Correlate administrator browser sessions with settings-change events to detect anomalous timing
Monitoring Recommendations
- Alert on outbound requests from admin browsers to unknown external domains during active WordPress sessions
- Monitor the wp_options table for unexpected writes to plugin-related keys
- Track HTTP referer headers on requests that modify plugin configuration and flag cross-origin submissions
How to Mitigate CVE-2025-31034
Immediate Actions Required
- Deactivate the Customize Login Page plugin until a patched version is available from the vendor
- Instruct administrators to log out of WordPress before browsing untrusted sites
- Restrict WordPress admin panel access by IP allowlist where operationally feasible
- Audit recent changes to plugin settings and revert any unauthorized modifications
Patch Information
At the time of the last NVD update, no fixed version has been published. The vulnerability affects all releases up to and including 1.1. Administrators should monitor the Patchstack Vulnerability Report and the WordPress plugin repository for an updated release that implements nonce validation.
Workarounds
- Remove the plugin and replace it with a maintained alternative that enforces WordPress nonce checks
- Deploy a Web Application Firewall (WAF) rule to block cross-origin POST requests to wp-admin endpoints
- Configure browsers or the WordPress admin to use SameSite=Strict session cookies to reduce CSRF exposure
- Limit administrator accounts to the minimum number required and enforce short session lifetimes
