CVE-2026-44442
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedERPNext is a free and open source Enterprise Resource Planning tool. Prior to 16.9.1, certain endpoints failed to enforce proper authorization checks, allowing users to modify data beyond their permitted role. This vulnerability is fixed in 16.9.1.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceERPNext versions prior to 16.9.1 contain a Broken Access Control vulnerability where certain API endpoints fail to enforce proper authorization checks. This allows authenticated users to modify data beyond what their assigned role permissions should permit, potentially enabling privilege escalation or unauthorized data tampering.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Determine installed ERPNext versionAccess the ERPNext dashboard and navigate to 'Help' > 'About' or execute the bench command: bench version. Alternatively, check the sites/[sitename]/site_config.json file for the frappe version, or query the database table 'tabAgent' or 'tabVersion' if accessible.Affected if The displayed version is below 16.9.1 (e.g., 16.8.x, 16.7.x, earlier) or the frappe version field shows a build prior to version 16.9.1.
-
Identify active API endpointsReview your ERPNext instance's API documentation at /api/method or check the router.js files in the apps/erpnext directory. Use server logs or proxy logs to enumerate which API endpoints are being called, particularly those handling data creation, modification, or deletion.Affected if The system exposes REST API endpoints (such as /api/resource/* or /api/method/*) that accept authenticated user requests for sensitive operations like creating, updating, or deleting records.
-
Verify role permission configurationLog in as a system administrator and navigate to: 'Settings' > 'Role Permission Manager'. Select a non-administrative role (e.g., Stock User, Accounts User) and review which document types and specific actions (read, write, delete, execute) are permitted. Cross-reference with the expected baseline permissions for that role.Affected if Non-administrative roles have elevated permissions (write, delete, or execute) on document types that should be restricted, or permissions appear inconsistent with the defined role responsibilities.
-
Test API authorization enforcementUsing an authenticated session with a limited-role user account, attempt to access or modify data outside your role's permitted scope via API calls. For example, try to update a Purchase Order using a Stock User account, or access HR documents using an Accounts role. Capture the HTTP response codes and data returned.Affected if The API accepts and processes requests that should be denied based on role permissions, returning success responses (200/201) instead of 403 Forbidden, or returns restricted data to unauthorized users.
Your environment is affected if ERPNext version is below 16.9.1 AND API endpoints handling sensitive data are accessible to users with roles that should not have permission to perform those operations.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped16.9.1
Upgrade ERPNext to version 16.9.1 or later to apply the authorization fix. Prior to production deployment, verify that role-based access controls are functioning correctly on affected endpoints.
16.9.1
- Backup your existing ERPNext database and application data before attempting any upgrade
- Review the ERPNext 16.9.1 release notes for any specific migration requirements
- Upgrade ERPNext to version 16.9.1 using your deployment method (bench update or equivalent)
- After upgrade, verify that the authorization checks are properly enforced on affected endpoints
- Test that users can only access data within their permitted roles
