## Overview

Frappe ERPNext before 15.119.1 and 16.x before 16.32.0 contains a server-side template injection vulnerability because user-controlled message fields are not validated before template rendering, allowing expressions to run in an unrestricted context. Authenticated attackers holding a common operational role can inject template expressions to read and write arbitrary database data, delete documents, send outbound requests from the server, and send mail from the site.
