Description Andrej Nemec 2017-02-21 04:31:40 EST
It was found that when OIDCUnAuthAction is set to pass the OICD_CLAIM_* headers are not being scrubbed. This allows for unauthenticated requests to /content/.

Sending the OIDC_CLAIM_preferred_username header then allows to spoof any existing username.
