Technical Analysis
Frappe ERPNext versions prior to 15.118.2 and 16.x prior to 16.30.0 contain a missing authorization vulnerability. Certain API endpoints do not enforce adequate authorization controls, enabling authenticated attackers with low-privileged accounts to read item master data that should be restricted based on their roles. This vulnerability has a CVSS 4.0 base score of 7.1, indicating a high severity due to network attack vector, low attack complexity, no user interaction, and high impact on confidentiality.
Potential Impact
An attacker with a low-privileged authenticated account can exploit this vulnerability to access sensitive item master data beyond their permitted access level. This unauthorized data disclosure could lead to information leakage within the affected ERP system. There is no indication of integrity or availability impact, and no known exploits in the wild have been reported.
Mitigation Recommendations
A fix is available in Frappe ERPNext versions 15.118.2 and 16.30.0 and later. Users should upgrade to these versions or later to remediate the vulnerability. Since this is not a cloud service, remediation depends on applying the vendor's official patches. Patch status is confirmed by the affected version ranges provided.
