Description

Issuu Panel plugin for WordPress before 1.6.6 contains a PHP file inclusion vulnerability that allows unauthenticated attackers to include remote or local files through the 'abspath' parameter. Attackers can send GET requests to menu/documento/requests/ajax-docs.php with a crafted abspath value passed to require() to execute remote PHP code or include local files. Exploitation evidence was first observed by the Shadowserver Foundation on 2023-10-20.
