Vulnerability Title
Frappe: Unauthenticated Workflow approval via confirm_action
Source: CVE Program / CVE List V5
Vulnerability 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.
