CVE-2025-22768: Rocket Media Library CSRF Vulnerability

CVE-2025-22768 Overview

CVE-2025-22768 is a Cross-Site Request Forgery (CSRF) vulnerability in the WordPress plugin "Rocket Media Library Mime Type" developed by JinHan Park. This vulnerability allows attackers to leverage CSRF as an attack vector to inject Stored Cross-Site Scripting (XSS) payloads into the application. The chained CSRF-to-Stored-XSS attack pattern significantly increases the potential impact, as successful exploitation can lead to persistent malicious script execution in the context of authenticated users' browsers.

Critical Impact

Attackers can exploit CSRF weaknesses to inject persistent XSS payloads that execute whenever users access affected pages, potentially leading to session hijacking, credential theft, and unauthorized administrative actions.

Affected Products

• Rocket Media Library Mime Type plugin versions up to and including 2.1.0
• WordPress installations using vulnerable versions of the plugin
• All users with access to WordPress sites running the affected plugin

Technical Details for CVE-2025-22768

Vulnerability Analysis

This vulnerability represents a dangerous attack chain combining two distinct web application security weaknesses. The primary flaw is a Cross-Site Request Forgery (CSRF) vulnerability classified under CWE-352, which stems from missing or improper validation of anti-CSRF tokens in the plugin's administrative functionality.

The lack of proper CSRF protection allows an attacker to craft malicious requests that, when executed by an authenticated administrator, can modify plugin settings or inject content without the user's knowledge or consent. When combined with insufficient input sanitization, this CSRF weakness enables the injection of Stored XSS payloads that persist in the WordPress database.

The network-based attack vector requires user interaction, specifically an authenticated user must visit a malicious page or click a crafted link while logged into their WordPress site. The vulnerability affects confidentiality, integrity, and availability across security boundaries, as malicious scripts can access sensitive data, modify page content, and disrupt normal site functionality.

Root Cause

The root cause of this vulnerability lies in the absence of proper CSRF token validation mechanisms within the Rocket Media Library Mime Type plugin's form handling and administrative functions. WordPress provides built-in nonce verification functions such as wp_verify_nonce() and check_admin_referer() that should be implemented to validate the legitimacy of form submissions.

Additionally, the plugin fails to properly sanitize and escape user-controlled input before storing it in the database or rendering it in the browser, creating the secondary Stored XSS condition. The combination of these two missing security controls creates the exploitable attack chain.

Attack Vector

The attack follows a multi-stage exploitation pattern:

1. An attacker identifies that the Rocket Media Library Mime Type plugin lacks CSRF protection on sensitive administrative functions
2. The attacker crafts a malicious HTML page containing a hidden form that submits a request to the vulnerable plugin endpoint
3. This request includes XSS payload data designed to be stored by the plugin
4. The attacker tricks an authenticated WordPress administrator into visiting the malicious page
5. The victim's browser automatically submits the forged request using their active session credentials
6. The XSS payload is stored in the WordPress database without proper sanitization
7. When any user subsequently views pages where the injected content is rendered, the malicious script executes

The attack can be delivered through phishing emails, compromised websites, or social engineering techniques targeting WordPress administrators. For detailed technical information about this vulnerability, refer to the Patchstack Vulnerability Advisory.

Detection Methods for CVE-2025-22768

Indicators of Compromise

• Unexpected or unauthorized changes to plugin settings or content within the Rocket Media Library Mime Type plugin configuration
• Suspicious JavaScript code or iframe tags appearing in database entries related to the plugin
• Web server access logs showing POST requests to plugin endpoints from external referrers
• User reports of browser warnings, pop-ups, or unexpected behavior when accessing WordPress administrative pages

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect and block requests with potential XSS payloads targeting WordPress plugin endpoints
• Configure Content Security Policy (CSP) headers to restrict script execution and report violations
• Deploy file integrity monitoring to detect unauthorized modifications to plugin files
• Utilize WordPress security plugins that provide real-time scanning for known vulnerabilities and suspicious database content

Monitoring Recommendations

• Enable detailed logging for WordPress administrative actions and form submissions
• Monitor for unusual patterns in administrative activity, particularly settings changes occurring without corresponding user sessions
• Implement browser-based XSS protection monitoring through CSP violation reports
• Regularly audit database content for unexpected script tags or encoded JavaScript payloads

How to Mitigate CVE-2025-22768

Immediate Actions Required

• Update the Rocket Media Library Mime Type plugin to the latest available version that addresses this vulnerability
• If no patch is available, consider temporarily deactivating the plugin until a security fix is released
• Review and audit recent plugin configuration changes for potential unauthorized modifications
• Implement Web Application Firewall rules to block suspicious requests targeting the plugin
• Educate WordPress administrators about phishing attacks and the importance of verifying link sources

Patch Information

Organizations should monitor the plugin's official WordPress repository and the Patchstack Vulnerability Advisory for updates regarding security patches. Ensure that automatic updates are enabled for WordPress plugins, or establish a routine patch management process to apply security updates promptly.

Workarounds

• Temporarily disable the Rocket Media Library Mime Type plugin if it is not critical to site operations
• Restrict administrative access to trusted IP addresses using .htaccess or firewall rules
• Implement additional CSRF protection at the web server level using security modules or WAF configurations
• Deploy Content Security Policy headers to mitigate the impact of potential XSS exploitation

# WordPress .htaccess - Restrict wp-admin access by IP
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{REQUEST_URI} ^/wp-admin
RewriteCond %{REMOTE_ADDR} !^192\.168\.1\.100$
RewriteRule ^(.*)$ - [R=403,L]
</IfModule>
