Description

Impact _What kind of vulnerability is it? Who is impacted?_ Anyone leveraging the `SignedHttpRequest`protocol or the `SignedHttpRequestValidator`is vulnerable. Microsoft.IdentityModel trusts the `jku`claim by default for the `SignedHttpRequest`protocol. This raises the possibility to make any remote or local `HTTP GET` request. Patches _Has the problem been patched? What versions should users upgrade to?_ The vulnerability has been fixed in Microsoft.IdentityModel.Protocols.SignedHttpRequest. Users should update all their Microsoft.IdentityModel versions to 7.1.2 (for 7x) or higher, 6.34.0 (for 6x) or higher, if using Microsoft.IdentityModel.Protocols.SignedHttpRequest. Workarounds _Is there a way for users to fix or remediate the vulnerability without upgrading?_ No, users must upgrade.
