How to fix?

There is no fixed version for RHEL:7 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:7 relevant fixed versions and status.

A flaw was found in openshift/oauth-proxy. The proxy sets authenticated identity headers using only dash-variant keys (X-Forwarded-User) but does not strip underscore-variant keys (X_Forwarded_User) from incoming requests. WSGI and PHP frameworks normalize both variants to the same variable, allowing an authenticated low-privilege user to smuggle a forged identity that may override the legitimate authenticated identity in the upstream application.
