CVE-2023-6291 is a high-severity vulnerability (CVSS 7.1) in Keycloak's redirect_uri validation logic, affecting various Red Hat products including Keycloak, OpenShift Container Platform, and Single Sign-On. This flaw allows an attacker to bypass explicitly allowed hosts, potentially leading to the theft of access tokens and user impersonation. While the attack requires user interaction (UI:R), it can be executed remotely (AV:N) with low complexity (AC:L), resulting in low impact to confidentiality, integrity, and availability (C:L/I:L/A:L). Currently, there is no evidence of active exploitation, publicly available exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
