Description
CVE-2026-119144 is a server-side template injection vulnerability in the Frappe Framework affecting versions before 15.111.0 and 16.x before 16.21.0. It arises because user-controlled message fields are rendered as templates without proper neutralization, allowing an authenticated attacker with common operational privileges to inject and execute arbitrary template expressions on the server.
