Protection mechanism failure in CGM CLININET before 2025.MS3 allows remote attackers to influence browser behavior via missing HTTP headers. The web application omits response headers governing framing, MIME handling, caching, cross-origin isolation, and transport security. Exploitation requires a user's browser to process attacker-controlled content alongside the application, with the published impact limited to browser-side integrity.
