Overview

Affected versions of this package are vulnerable to Missing Encryption of Sensitive Data due to the incomplete parsing of the server hello message. An attacker can establish a connection using an unverified ciphersuite by exploiting the client's downgrade capability from TLS1.3 to TLS1.2. Note: This is only exploitable if the client has downgrade capability enabled.
