Summary
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.

Fencer Intel keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.
The maintainers of frappe/frappe published their own advisory on GitHub. Reviewed sources take precedence over it.
CPEs and fixed versions use Anchore's correction of NVD's data: Added CPE configurations because not yet analyzed by NVD.
