NewCVE-2025-6444 (opens in a new tab)How to fix?
Upgrade ServiceStack.Text to version 8.6.0 or higher.
Overview
ServiceStack.Text is a set of JSON, JSV and CSV text serializers
Affected versions of this package are vulnerable to External Control of File Name or Path in the url parameter to the GetErrorResponse method. An attacker can relay NTLM credentials in the context of the current user by supplying a URI with the file:// scheme.
Note: The package's developers point out that the security impact of this method's ability to access local file paths is minimal because such access is exposed by the native .Net WebRequest.Create(url) that this package provides a wrapper for. So no greater risk is introduced by the wrapper function.
