Last modified
CVE-2026-49332 is a high-severity vulnerability rated 8.5/10 on the CVSS scale. A flaw was found in openshift/oauth-proxy.

EPSS estimates a 0.23% chance of exploitation in the next 30 days.
Description
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.
