Technical Analysis
This vulnerability affects Frappe ERPNext versions >=0 and <15.110.0, and >=16.0.0-beta.1 and <16.21.0. Certain API endpoints fail to enforce authorization checks on record status changes, enabling authenticated users with low privileges to perform unauthorized data modifications beyond their assigned roles. The CVSS 4.0 base score is 5.3, indicating a medium severity impact. No known exploits are reported in the wild. The vulnerability is due to missing authorization enforcement rather than authentication bypass or privilege escalation.
Potential Impact
Authenticated users with low privileges can modify data beyond their permitted roles by exploiting endpoints that lack proper authorization checks. This can lead to unauthorized data changes within the ERP system, potentially impacting data integrity and business processes. The vulnerability does not allow unauthenticated access or privilege escalation but bypasses intended role-based restrictions.
Mitigation Recommendations
A fix is available in Frappe ERPNext versions 15.110.0 and 16.21.0 and later. Users should upgrade to these versions or later to remediate the vulnerability. Patch status is confirmed by the affected version ranges indicating fixed versions. No additional mitigation steps are specified.
