Technical details
The vulnerability is a stored client-side template injection (CSTI) in the product name field that reaches the Vue.js template compiler. An authenticated attacker with product creation/editing privileges can inject Vue template expressions using double-brace syntax (e.g., {{ constructor.prototype }}) to bypass the template sandbox via prototype chain traversal, retrieve the Function constructor, and execute arbitrary JavaScript in the application origin for all users viewing the product record.
