NGINX Ingress Controller may mishandle the HTTP response from an OAuth IdP and allow an attacker to acquire unauthenticated access to protected paths before the proper external authentication can happen.\n\n\n\nImpact\nThis vulnerability may allow remote attackers \n\nunauthenticated\n\n access to protected \n\npaths. There is no control plane exposure; this is a data plane issue only.\n\n\n\n\nNote: Software versions which have reached End of Technical Support (EoTS) are not evaluated.",
