CVE-2025-32518: ALD Login Page CSRF Vulnerability

CVE-2025-32518 Overview

CVE-2025-32518 is a Cross-Site Request Forgery (CSRF) vulnerability in the ALD Login Page WordPress plugin developed by hossainawlad. The flaw affects all versions through 1.1 and enables stored Cross-Site Scripting (XSS) when an authenticated administrator is tricked into submitting a forged request. The vulnerability is tracked under CWE-352 and stems from missing or improper CSRF token validation on plugin configuration endpoints. Successful exploitation persists attacker-controlled scripts in the WordPress database, executing in the browser of any subsequent visitor or administrator.

Critical Impact
An attacker can plant persistent JavaScript in WordPress administrative pages by tricking an authenticated administrator into visiting a malicious link, leading to session theft, account takeover, or further site compromise.

Affected Products

hossainawlad ALD Login Page (ald-login-page) plugin for WordPress
All versions from initial release through 1.1
WordPress sites with the plugin installed and active

Technical Details for CVE-2025-32518

Vulnerability Analysis

The vulnerability combines two weaknesses in the ald-login-page plugin. The plugin lacks anti-CSRF protection on state-changing requests, and it fails to sanitize user-supplied input before storing it in the database. An attacker hosts a malicious page containing a forged form or request targeting the plugin's settings endpoint. When an authenticated administrator visits the page, the browser submits the request with valid session cookies. The plugin processes the request and stores attacker-supplied HTML or JavaScript in plugin options.

The injected payload executes whenever the affected page is rendered, producing a stored XSS condition. Because the script runs in the administrator's authenticated context, the attacker can perform any action the administrator can, including creating new privileged users, modifying plugins, or exfiltrating session data.

Root Cause

The root cause is the absence of WordPress nonce verification using wp_verify_nonce() or check_admin_referer() on form submissions handled by the plugin. Combined with missing output encoding through functions such as esc_html() or esc_attr(), the plugin permits forged requests to write unsanitized script content into persistent storage.

Attack Vector

Exploitation requires user interaction. The attacker delivers a crafted URL or web page to a logged-in WordPress administrator through phishing, social engineering, or a malicious advertisement. The forged request is submitted across origins, leveraging the administrator's existing session. No credentials are required from the attacker, and the scope changes because the injected script executes in the trusted application origin. See the Patchstack WordPress Vulnerability Report for advisory details.

Detection Methods for CVE-2025-32518

Indicators of Compromise

Unexpected <script> tags or JavaScript event handlers stored in plugin option rows within the wp_options table
Administrative accounts created without a corresponding audit trail in WordPress user logs
Outbound HTTP requests from administrator browsers to unfamiliar domains after visiting the WordPress admin dashboard
Modifications to plugin settings without matching entries in the web server access log from administrative IP addresses

Detection Strategies

Inspect the wp_options table for plugin-related rows containing HTML or JavaScript syntax, such as <script, onerror=, or javascript: substrings
Review web server access logs for POST requests to plugin endpoints lacking a same-origin Referer header
Monitor WordPress audit logs for plugin configuration changes correlated with unusual referrer values or off-hours administrator activity

Monitoring Recommendations

Enable a WordPress activity logging plugin to capture all plugin setting changes with originating user, IP, and timestamp
Deploy a Content Security Policy (CSP) in report-only mode to surface inline scripts injected into administrative pages
Alert on creation of new administrator accounts or changes to existing user roles that occur outside scheduled maintenance windows

How to Mitigate CVE-2025-32518

Immediate Actions Required

Deactivate and remove the ald-login-page plugin until a vendor-supplied patch is available
Audit the wp_options table and plugin configuration records for any injected script content and remove malicious entries
Force password resets and re-issue session tokens for all WordPress administrator accounts
Review installed plugins, themes, and user accounts for unauthorized changes introduced during the exposure window

Patch Information

At the time of NVD publication, no fixed version is listed. The Patchstack advisory identifies all versions through 1.1 as vulnerable. Administrators should monitor the Patchstack WordPress Vulnerability Report and the WordPress plugin repository for an updated release that adds nonce validation and input sanitization.

Workarounds

Restrict access to /wp-admin/ by source IP using web server access controls or a web application firewall
Apply a virtual patch through a WAF rule blocking POST requests to plugin endpoints that lack a valid _wpnonce parameter and same-origin Referer header
Require administrators to use a dedicated browser profile for WordPress administration, isolating session cookies from general browsing
Enable two-factor authentication on all administrative accounts to limit account takeover impact if XSS-driven session theft occurs

bash
