CVE-2026-44442Network attack vector

Authenticated document modification via missing authorization

Published May 13, 2026 · Updated May 13, 2026

Missing authorization in ERPNext before 16.9.1 allows remote authenticated users to modify documents beyond their assigned role. Certain endpoints perform document changes without enforcing the requesting user's role authorization, but their names are undisclosed. A low-privileged account is sufficient, and no user interaction is required; the published impact is bounded to unauthorized data modification.
