CyberRota Analysis
AI-GeneratedThe WPLP Cookie Consent plugin for WordPress is vulnerable to Stored Cross-Site Scripting due to inadequate input sanitization and output escaping in the 'wpl_user_preference' parameter, affecting all versions up to 4.4.1. This vulnerability allows unauthenticated attackers to inject malicious scripts that execute when users access compromised pages, posing a significant risk to user data and site integrity. WordPress site administrators using this plugin should prioritize immediate updates to mitigate potential exploitation.
Original NVD Description
The Cookie Banner for GDPR / CCPA – WPLP Cookie Consent plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'wpl_user_preference' parameter in all versions up to, and including, 4.4.1 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 consent-logging AJAX endpoint is registered for unauthenticated users and its required nonce (wpl_consent_logging_nonce) is publicly emitted via wp_localize_script on the frontend, meaning any unauthenticated site visitor can plant a payload without any prior authentication or privileged access.
