Summary

A flaw was found in the Quarkus Qute template engine. When the {#eval} section helper processes a sub-template, it fails to pass the parent template's content type information. This bypasses standard escaping mechanisms, allowing untrusted data to be output as raw, unescaped text. This vulnerability can lead to Cross-Site Scripting (XSS) and JSON Injection, potentially allowing a remote attacker to execute arbitrary code in a user's browser or manipulate data.

Risk Assessment

The XSS and JSON Injection vulnerability may allow an attacker to execute arbitrary JavaScript in the victim's browser, steal sessions, or manipulate application data. Organizations using Quarkus Qute to render content from untrusted sources are exposed to client-side attacks and data injection.

Recommendation

Update Quarkus to a version containing the fix for this flaw, or avoid using the {#eval} helper with untrusted data. Apply additional escaping and output validation mechanisms in Qute templates.
