Technical Analysis
Frappe ERPNext versions prior to 15.112.0 contain a missing authorization vulnerability that permits authenticated users holding a common operational role to modify records beyond their permission boundaries. This occurs due to missing validation checks in specific API endpoints, enabling attackers to change fields on record types they should not have access to. The vulnerability does not require user interaction and has a network attack vector with low complexity and low impact on confidentiality and integrity.
Potential Impact
Authenticated users with limited operational roles can escalate their privileges to modify data they are not authorized to change, potentially leading to unauthorized data tampering within the ERP system. This could affect data integrity but does not directly impact confidentiality or availability according to the CVSS vector.
Mitigation Recommendations
A fix is available in Frappe ERPNext version 15.112.0 and later. Users should upgrade to version 15.112.0 or above to remediate this vulnerability. No additional vendor advisory was provided, so check the official Frappe ERPNext release notes or security advisories for confirmation and further guidance.
