CyberRota Analysis
AI-GeneratedThe Invisible Anti-Spam & CAPTCHA plugin for WordPress is vulnerable to Stored Cross-Site Scripting due to inadequate input sanitization and output escaping in the 'action' parameter. This flaw allows unauthenticated attackers to inject malicious scripts that execute when users access affected pages, potentially compromising user data and site integrity. WordPress site administrators using this plugin should prioritize immediate updates to mitigate the risk of exploitation.
Original NVD Description
The Invisible Anti-Spam & CAPTCHA — reCAPTCHA Alternative for All Forms plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'action' parameter in all versions up to, and including, 5.1 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The stored payload is written by any unauthenticated admin-ajax.php request whose action value matches an entry in the plugin's explicit-actions list, which is auto-populated for common form builders at activation and requires no authentication gate to reach the save path.
