How to fix?

There is no fixed version for Ubuntu:22.04 qtbase-opensource-src.

NVD Description

Note: Versions mentioned in the description apply only to the upstream qtbase-opensource-src package and not the qtbase-opensource-src package as distributed by Ubuntu. See How to fix? for Ubuntu:22.04 relevant fixed versions and status.

An issue was discovered in Qt before 5.15.14, 6.x before 6.2.9, and 6.3.x through 6.5.x before 6.5.1. 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.
