CVE-2022-4137 is a reflected cross-site scripting (XSS) vulnerability in the 'oob' OAuth endpoint of Red Hat Keycloak and Single Sign-On, stemming from incorrect null-byte handling. This medium-severity flaw (CVSS 6.1) requires user interaction with a malicious link to inject an arbitrary URI into a Keycloak error page, potentially compromising or allowing an attacker to collect user details. While no active exploitation, public exploit code, or significant community discussion has been observed, organizations using affected products should be aware of this risk.
