Summary

The Qt Framework QWebSocket authentication handling in the Qt WebSockets module affects versions from 6.6.0 before 6.8.10, from 6.9.0 before 6.11.3, and from 6.12.0 before 6.12.1. Sensitive information in a resource is not removed before the resource is reused (CWE-226), which causes an information disclosure. A remote attacker without privileges may read sensitive information, and exploitation requires user interaction.
