What the vulnerability does
01Description
The ShopLentor – WooCommerce Builder for Elementor & Gutenberg +21 Modules – All in One Solution plugin for WordPress is vulnerable to Email Relay Abuse in all versions up to, and including, 3.3.2. This is due to the lack of validation on the 'send_to', 'product_title', 'wlmessage', and 'wlemail' parameters in the 'woolentor_suggest_price_action' AJAX endpoint. This makes it possible for unauthenticated attackers to send arbitrary emails to any recipient with full control over the subject line, message content, and sender address (via CRLF injection in the 'wlemail' parameter), effectively turning the website into a full email relay for spam or phishing campaigns.
Explanation of Vulnerability in Simple Terms
