Affected versions of this package are vulnerable to Permissive Cross-domain Policy with Untrusted Domains via the Access-Control-Allow-Origin header in the server response. An attacker can access sensitive local files by enticing a user to visit a malicious website while the server is running locally, enabling unauthorized cross-origin requests to endpoints such as /media that serve files from the local filesystem. This can result in the exposure of confidential data to an external attacker.
