Description OSIDB Bzimport 2025-06-24 13:28:24 UTC 
In some mod_ssl configurations on Apache HTTP Server 2.4.35 through to 2.4.62, an access control bypass by trusted clients is possible using TLS 1.3 session resumption. Configurations are affected when mod_ssl is configured for multiple virtual hosts, with each restricted to a different set of trusted client certificates (for example with a different SSLCACertificateFile/Path setting). In such a case, a client trusted to access one virtual host may be able to access another virtual host, if SSLStrictSNIVHostCheck is not enabled in either virtual host.
