MEDIUM

Qt <5.15.14, 6.x <6.2.9, 6.3.x-6.5.x <6.5.1 - Info Disclosure

Title source: llm
STIX 2.1

Description

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.
