What is CVE-2026-48543?

Krayin CRM versions up to 2.2.6 are vulnerable to a serious stored client-side template injection flaw. This vulnerability allows authenticated attackers to inject malicious Vue.js template expressions into the web form description field. By leveraging double-brace template syntax, attackers can manipulate the Vue template compiler, initiating prototype chain traversal. This leads to the retrieval of the Function constructor, enabling execution of arbitrary JavaScript in the context of any user who accesses the compromised web form, posing significant security risks.

Affected Version(s)

laravel-crm 0 <= 2.2.6
