What is CVE-2026-48542?

Krayin CRM versions prior to 2.2.6 are vulnerable to a stored client-side template injection attack. This vulnerability enables authenticated attackers to execute arbitrary JavaScript in the browsers of other users by manipulating the product name field with crafted Vue.js template expressions. By exploiting double-brace syntax, attackers can reach the Vue template compiler, allowing them to perform prototype chain traversal, retrieve the Function constructor, and run malicious JavaScript in the application context whenever the affected product record is accessed by other users.

Affected Version(s)

laravel-crm 0 <= 2.2.6
