CVE-2026-34582

A flaw was found in Botan, a C++ cryptography library. The TLS 1.3 implementation in Botan allows application data to be processed before the TLS handshake is fully completed. A remote attacker can exploit this by omitting critical client authentication messages, such as the Certificate, CertificateVerify, and Finished messages, and instead sending application data. This vulnerability enables a client to bypass server-enforced client authentication, potentially leading to unauthorized access.
