How to fix?

There is no fixed version for RHEL:9 openshift4/ose-oauth-proxy-rhel9.

NVD Description

Note: Versions mentioned in the description apply only to the upstream openshift4/ose-oauth-proxy-rhel9 package and not the openshift4/ose-oauth-proxy-rhel9 package as distributed by RHEL. See How to fix? for RHEL:9 relevant fixed versions and status.

A flaw was found in openshift/oauth-proxy. On paths configured to bypass authentication (skip-auth-regex), the proxy forwards client-supplied identity headers (X-Forwarded-User, X-Forwarded-Email, X-Forwarded-Access-Token) to the upstream application without stripping them. An unauthenticated attacker can inject forged identity headers on whitelisted paths.
