CVE-2026-48540
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 lead title field.
Does this matter?
Lower severity and a low EPSS score (0.17%). Track it; it rarely justifies an emergency change on its own.
Description
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 lead title field. Attackers can craft a lead title 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 lead record.
