Summary
Krayin CRM through 2.2.6 contains a stored client-side template injection vulnerability that allows authenticated attackers to execute arbitrary JavaScript in other users' browsers by injecting Vue.js template expressions into the web form description field. Attackers can craft a web form description containing double-brace template syntax that reaches the Vue template compiler, enabling prototype chain traversal to retrieve the Function constructor and execute attacker-supplied JavaScript in the application origin for every user who views the affected web form.
