Description
WordPress Insert PHP plugin versions before 3.3.1 contain a PHP code injection vulnerability that allows unauthenticated attackers to execute arbitrary PHP code by injecting malicious shortcodes through the WordPress REST API. Attackers can send POST requests to the wp-json/wp/v2/posts endpoint with crafted content containing insert_php shortcodes to include and execute remote PHP files on the server.
