CVE-2025-23048 is an access-control bypass in Apache HTTP Server mod_ssl affecting versions 2.4.35 through 2.4.63. In deployments with multiple TLS virtual hosts that each trust different client-certificate authorities, TLS 1.3 session resumption can permit a client trusted for one virtual host to access another virtual host with a different trusted-client-certificate policy. The issue applies when SSLStrictSNIVHostCheck is disabled in both virtual hosts.
