NVD Description

Note: Versions mentioned in the description apply only to the upstream openshift4/ose-oauth-proxy package and not the openshift4/ose-oauth-proxy package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

A flaw was found in oauth-proxy. The application fails to properly validate the destination redirect parameter (rd) during post-login redirection. A remote attacker can exploit this vulnerability by enticing a user to follow a specially crafted link, resulting in the user being redirected to an arbitrary external website after authenticating. This open redirect can be leveraged to conduct phishing attacks or credential theft.
