CVE-2019-3878 is a high-severity authentication bypass vulnerability affecting mod_auth_mellon versions prior to 0.14.2, specifically impacting configurations where Apache acts as a reverse proxy requiring authenticated users. An attacker can bypass authentication by sending specially crafted HTTP headers typically used for SAML ECP, leading to full compromise of confidentiality, integrity, and availability. While the CVSS score is 8.1 (HIGH) with a low EPSS score, there is no evidence of active exploitation, public exploit code, or significant community discussion.
