CVE-2024-12797 is an improper server-authentication validation flaw in OpenSSL's RFC 7250 Raw Public Key (RPK) support. In affected OpenSSL 3.2, 3.3, and 3.4 releases, a TLS or DTLS client configured with SSL_VERIFY_PEER may allow a handshake to complete when the server's RPK does not match an expected public key, rather than aborting the handshake. Applications that explicitly retrieve the verification result with SSL_get_verify_result() and reject failed verification remain protected. The flaw was introduced with the initial RPK implementation in OpenSSL 3.2.
