Janssen Project: JWE Request Object Signature Verification Bypass in jans-auth-server

Description

The Janssen Project is an open-source identity and access management (IAM) platform. Prior to 2.0.0, jans-auth-server accepts unsigned JWE request objects because JwtAuthorizationRequest skips inner signature validation when jwe.getSignedJWTPayload() returns null, and AuthzRequestService.processRequestObject() does not reject the unrecognized RSA-OAEP algorithm when forceSignedRequestObject=true. This issue is fixed in version 2.0.0.
