CVE-2025-52802: Import YouTube Videos Auth Bypass Flaw

CVE-2025-52802 Overview

A Missing Authorization vulnerability has been identified in the "Import YouTube videos as WP Posts" WordPress plugin developed by enguerranws. This security flaw allows attackers to exploit incorrectly configured access control security levels, enabling unauthorized actions within the WordPress installation. The vulnerability stems from a lack of proper authorization checks (CWE-862), allowing unauthenticated users to perform actions that should be restricted to authorized users.

Critical Impact

Unauthenticated attackers can exploit broken access controls to perform unauthorized modifications to WordPress content and settings, potentially compromising site integrity.

Affected Products

• Import YouTube videos as WP Posts plugin versions up to and including 2.1
• WordPress installations using the vulnerable import-youtube-videos-as-wp-post plugin

Technical Details for CVE-2025-52802

Vulnerability Analysis

This vulnerability is classified as Missing Authorization (CWE-862), a common weakness in WordPress plugins where critical functionality lacks proper capability checks or nonce verification. The vulnerability allows remote attackers to access protected functionality without authentication, as the plugin fails to verify user permissions before executing sensitive operations.

The network-accessible nature of this flaw means attackers can exploit it remotely without any prior authentication or user interaction. The primary impact is on data integrity, where unauthorized modifications can be made to WordPress posts and content.

Root Cause

The root cause of this vulnerability is the absence of proper authorization checks within the plugin's code. WordPress plugins should implement capability checks using functions like current_user_can() and verify nonces to ensure requests originate from authorized users. The "Import YouTube videos as WP Posts" plugin fails to implement these security measures, leaving administrative or privileged functionality exposed to unauthenticated users.

Attack Vector

The attack vector is network-based, requiring no authentication or user interaction. An attacker can send crafted HTTP requests directly to vulnerable plugin endpoints. Since the plugin lacks proper access control verification, these requests are processed as if they came from an authorized user.

The exploitation scenario involves:

1. Identifying WordPress installations running the vulnerable plugin version (2.1 or earlier)
2. Sending unauthenticated requests to plugin endpoints that lack authorization checks
3. Performing unauthorized actions such as importing content, modifying settings, or manipulating WordPress posts

Detection Methods for CVE-2025-52802

Indicators of Compromise

• Unexpected WordPress posts created from YouTube video imports without administrator action
• Unauthorized modifications to plugin settings or configurations
• Anomalous HTTP requests to plugin-specific endpoints from unknown sources
• Log entries showing access to plugin functionality without corresponding user authentication

Detection Strategies

• Review WordPress access logs for requests to /wp-admin/ and plugin-specific AJAX endpoints lacking valid authentication cookies
• Monitor for unusual patterns of POST requests targeting the import-youtube-videos-as-wp-post plugin
• Implement Web Application Firewall (WAF) rules to detect and block unauthorized access attempts to vulnerable endpoints
• Conduct regular WordPress plugin audits to identify unauthorized configuration changes

Monitoring Recommendations

• Enable WordPress debug logging to capture detailed request information
• Configure alerting for new post creation events that occur outside normal administrative workflows
• Implement file integrity monitoring to detect unauthorized changes to plugin files
• Deploy real-time monitoring for suspicious HTTP request patterns targeting WordPress plugin endpoints

How to Mitigate CVE-2025-52802

Immediate Actions Required

• Deactivate and remove the "Import YouTube videos as WP Posts" plugin until a patched version is available
• Audit WordPress posts and settings for any unauthorized modifications
• Review server access logs for evidence of exploitation attempts
• Implement temporary access restrictions to WordPress admin endpoints

Patch Information

As of the published CVE data, versions through 2.1 are confirmed vulnerable. Plugin users should monitor the official WordPress plugin repository and the Patchstack Vulnerability Report for updates regarding patched versions. Until a fix is released, the plugin should be removed from production WordPress installations.

Workarounds

• Disable the plugin entirely until a security patch is released
• Implement Web Application Firewall (WAF) rules to block unauthenticated requests to plugin endpoints
• Restrict access to /wp-admin/ and AJAX endpoints at the server level using IP allowlisting
• Use WordPress security plugins to add additional authorization layers to plugin functionality

# Example: Block plugin endpoints via .htaccess (Apache)
# Add to WordPress root .htaccess file
<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteCond %{REQUEST_URI} import-youtube-videos-as-wp-post [NC]
    RewriteCond %{HTTP_COOKIE} !wordpress_logged_in [NC]
    RewriteRule .* - [F,L]
</IfModule>
