## Technical details

Certain API endpoints in ERPNext fail to enforce proper authorization checks (CWE-862), allowing authenticated users with low privileges to access sensitive financial data they should not be permitted to view. The vulnerability requires valid authentication credentials and network access to the affected endpoints; no user interaction or elevated privileges are needed once authenticated. The impact is limited to confidentiality: attackers gain unauthorized read access to financial records.
