Description
TinyMCE Thumbnail Gallery plugin for WordPress before 1.1.0 contains a path traversal vulnerability that allows unauthenticated attackers to read arbitrary files via the href parameter. Attackers can send GET requests to /php/download-image.php with traversal sequences like ../../../../wp-config.php to retrieve database credentials and system files. Exploitation evidence was first observed by the Shadowserver Foundation on 2023-10-19.
