Technical details
The vulnerability is a cross-site scripting (XSS) and JSON injection flaw in the Qute {#eval} section helper that fails to pass parent template content type information when processing sub-templates, bypassing escaping mechanisms. An unauthenticated remote attacker can craft malicious input that is rendered as raw, unescaped text in the application's web output. Mitigation is available by switching from the {#eval} section syntax to the str:eval extension method.
