Executive Summary

ERPNext versions 15.103.1 and earlier are vulnerable to Server-Side Template Injection (SSTI). This means that an attacker who has permission to create or edit email templates can insert malicious template expressions. These expressions are then executed on the server when the email template is rendered.

Impact Analysis

This vulnerability allows an attacker with template editing permissions to execute arbitrary code on the server. This can lead to unauthorized actions, data exposure, or compromise of the server hosting ERPNext.
