What is CVE-2026-48540?

Krayin CRM versions up to 2.2.6 are susceptible to a stored client-side template injection vulnerability. This flaw allows authenticated attackers to inject malicious Vue.js template expressions into the lead title field, resulting in the execution of arbitrary JavaScript in the browsers of users who view the affected lead records. Attackers can exploit this issue by crafting lead titles that leverage double-brace syntax, enabling prototype chain traversal and retrieval of the Function constructor. This vulnerability poses a significant risk as it can lead to unauthorized JavaScript execution within the application context, affecting all users who access the compromised lead.

Affected Version(s)
