Detailsinfo

A vulnerability, which was classified as very critical, has been found in Red Hat OpenShift Container Platform (version unknown). Affected by this issue is an unknown function of the component Oauth Proxy. The manipulation with an unknown input leads to a privileges management vulnerability. Using CWE to declare the problem leads to CWE-269. The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor. Impacted is confidentiality, integrity, and availability. CVE summarizes:

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.

The advisory is shared for download at access.redhat.com. This vulnerability is handled as CVE-2026-49332 since 05/29/2026. The exploitation is known to be easy. The attack may be launched remotely.
