CVE-2020-14359 describes a critical authentication bypass vulnerability in all versions of Keycloak Gatekeeper and Red Hat Louketo Proxy. An attacker can bypass the Gatekeeper by sending HTTP requests with lowercase headers, which some web servers like Jetty accept, leaving protected resources exposed. This vulnerability carries a CVSS score of 7.3 (HIGH) due to its network-based attack vector, low attack complexity, and potential for partial compromise of confidentiality, integrity, and availability. While no active exploitation, public exploit code, or significant community discussion has been observed, organizations using affected products should prioritize patching to mitigate this risk.
