Overview

Affected versions of this package are vulnerable to Cleartext Transmission of Sensitive Information. Qt Network incorrectly parses the strict-transport-security (HSTS) header, allowing unencrypted connections to be established, even when explicitly prohibited by the server.

This happens if the case used for this header does not exactly match.
