Affected versions of this package are vulnerable to Server-side Request Forgery (SSRF) due to improper validation of filesystem paths in the ComponentRequestHandler process. An attacker can trigger outbound SMB authentication attempts from the server, potentially exposing NTLMv2 credential hashes of the Windows user running the process, by supplying a malicious UNC path in a request.
Note:
This is only exploitable if the application is running on a Windows host and component endpoints are exposed to untrusted networks.
