Description
The WordPress plugin Asset-Manager version 2.0 and below contains an unauthenticated arbitrary file upload vulnerability in upload.php. The endpoint fails to properly validate and restrict uploaded file types, allowing remote attackers to upload malicious PHP scripts to a predictable temporary directory.
