Executive Summary

This vulnerability occurs when the connection handshake fails during ALPN (Application-Layer Protocol Negotiation). The error message generated includes information controlled by the attacker (the ALPN protocols sent by the client) and this information is not properly escaped, potentially leading to security issues.

Impact Analysis

The vulnerability can allow an attacker to inject malicious content into error messages due to unescaped attacker-controlled input. This could lead to information disclosure or other security risks depending on how the error messages are handled or displayed.
