## Technical details

A stored client-side template injection (CSTI) vulnerability exists in Krayin CRM's Vue.js template handling, where user-supplied input in the web form description field is rendered without proper escaping. An authenticated attacker can inject Vue.js double-brace template syntax (e.g., `{{ "a".constructor.prototype.charAt.constructor("alert(origin)")() }}`) that reaches the Vue template compiler, enabling prototype chain traversal to access the Function constructor and execute arbitrary JavaScript. Every user viewing the affected web form triggers execution of the attacker's payload in the application's origin context.
