CVE-2025-25104 Overview
CVE-2025-25104 is a Cross-Site Request Forgery (CSRF) vulnerability affecting the URL-Preview-Box WordPress plugin (good-url-preview-box) developed by mraliende. This vulnerability allows attackers to perform unauthorized actions on behalf of authenticated users by tricking them into visiting a malicious webpage or clicking a crafted link.
Critical Impact
This CSRF vulnerability can be chained with Stored XSS, allowing attackers to execute malicious scripts in the context of authenticated users, potentially leading to account takeover, data theft, or further compromise of the WordPress installation.
Affected Products
- WordPress URL-Preview-Box plugin (good-url-preview-box) versions 1.20 and earlier
- WordPress installations utilizing the affected plugin versions

Technical Details for CVE-2025-25104
Vulnerability Analysis
This vulnerability is classified under CWE-352 (Cross-Site Request Forgery). The URL-Preview-Box plugin fails to properly validate or include anti-CSRF tokens (nonces) in its form submissions and state-changing requests. Without proper CSRF protection, the plugin cannot verify that requests originate from legitimate user interactions within the WordPress admin interface.
The vulnerability chain documented by Patchstack indicates this CSRF vulnerability can lead to Stored XSS, significantly amplifying its impact. An attacker can craft a malicious request that, when executed by an authenticated administrator, injects persistent malicious content into the plugin's stored data.
Root Cause
The root cause of this vulnerability stems from inadequate implementation of WordPress security best practices. Specifically, the plugin lacks proper nonce verification using WordPress functions like wp_nonce_field() and wp_verify_nonce() on form submissions and AJAX handlers. This architectural oversight allows external sites to forge requests that appear legitimate to the plugin.
Attack Vector
The attack vector requires social engineering to lure an authenticated WordPress administrator to a malicious webpage. The attacker-controlled page contains hidden forms or JavaScript that automatically submits forged requests to the vulnerable plugin endpoints. Since the victim's browser includes their authentication cookies with the request, the WordPress installation processes it as a legitimate administrative action.
The attack chain typically involves:
- Attacker identifies a WordPress site using the vulnerable URL-Preview-Box plugin
- Attacker crafts a malicious webpage containing forged requests targeting plugin functionality
- Attacker delivers the malicious link to an authenticated administrator via email, social media, or other channels
- When the administrator visits the malicious page, their browser executes the forged request
- The plugin processes the request, potentially storing malicious XSS payloads
Detection Methods for CVE-2025-25104
Indicators of Compromise
- Unexpected modifications to URL-Preview-Box plugin settings or stored data
- Unusual JavaScript or HTML content appearing in URL preview configurations
- Suspicious admin activity logs showing plugin changes without corresponding legitimate user sessions
- Users reporting unexpected behavior or redirects when viewing URL previews
Detection Strategies
- Review WordPress admin activity logs for plugin configuration changes made during periods of no expected administrative activity
- Implement Web Application Firewall (WAF) rules to detect and block CSRF attack patterns targeting WordPress plugins
- Monitor for suspicious outbound connections or script injections originating from stored content
- Conduct regular security audits of WordPress plugin configurations
Monitoring Recommendations
- Enable WordPress debug logging to capture detailed request information for security analysis
- Deploy endpoint detection solutions to monitor for browser-based attacks against administrative users
- Implement Content Security Policy (CSP) headers to mitigate the impact of any successful XSS injection
- Use SentinelOne Singularity XDR to detect anomalous WordPress administrative activities and potential exploitation attempts
How to Mitigate CVE-2025-25104
Immediate Actions Required
- Deactivate and remove the URL-Preview-Box plugin until a patched version is available
- Review plugin settings and stored data for any signs of tampering or malicious content
- Audit administrator accounts for any unauthorized changes or suspicious activity
- Consider implementing additional WordPress hardening measures and security plugins
Patch Information
As of the last NVD update, no official patch information has been published for this vulnerability. Administrators should monitor the Patchstack Vulnerability Report for updates on remediation options. Until a patch is released, the recommended approach is to remove or disable the affected plugin.
Workarounds
- Remove the URL-Preview-Box plugin entirely if its functionality is not critical
- Implement a Web Application Firewall (WAF) to filter malicious CSRF requests targeting WordPress
- Restrict administrative access to trusted IP addresses only
- Train administrators to recognize social engineering attempts and avoid clicking suspicious links while logged into WordPress
- Enable two-factor authentication for all WordPress administrator accounts to add an additional layer of security
