CVSS 7.5 HIGH
A flaw was found in the crypto/tls component. This vulnerability occurs during Transport Layer Security (TLS) session resumption when certificate authority (CA) settings are modified between the initial and resumed handshakes. An attacker could exploit this to bypass certificate validation, allowing a client or server to establish a connection that should have been rejected. This could lead to an authentication bypass under specific conditions.
