Red Hat OpenShift Container Platform 4: open redirect
Medium4.3CVE-2026-19078 · Published Aug 11, 2026 · updated Aug 14, 2026
A flaw was found in the oauth-server component. This open redirect vulnerability occurs when the 'then' parameter in the grant approval handler is not properly validated. A remote attacker can craft a malicious URL that, when approved or denied by an authenticated user, redirects them to an attacker-controlled website. This could enable phishing attacks, potentially tricking users into revealing sensitive information.
