Memphis Documents Library plugin for WordPress before 3.1.6 contains a path traversal vulnerability that allows unauthenticated attackers to read arbitrary files via the mdocs-img-preview parameter. Attackers can send GET requests with traversal sequences to mdocs_img_preview() in mdocs-downloads.php to download wp-config.php containing database credentials. Exploitation evidence was first observed by the Shadowserver Foundation on 2023-10-22.
