4.3Medium

Attack vector: Network
Complexity: Low
Privileges needed: Low
User interaction: None
Impact: Limited impact
Weakness: CWE-862

Impact

Authenticated low-privileged users can modify ERPNext data outside their assigned role permissions. An attacker only needs network access and valid user credentials on the instance.

Root cause

Certain API endpoints fail to enforce authorization checks against the calling user's assigned role.

Affected systems

Frappe ERPNext versions prior to 15.121.0, and 16.x versions prior to 16.34.0

CVSS v3.1 · CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N

Fix & remediation

Upgrade ERPNext to version 15.121.0, 16.34.0, or newer. No interim workaround is documented, so restrict access for untrusted authenticated users until the instance is updated.

shell

$ bench update --apps erpnext
