Lifecycle Timeline
2DescriptionGitHub Advisory
ERPNext is a free and open source Enterprise Resource Planning tool. Prior to 16.9.1, certain endpoints failed to enforce proper authorization checks, allowing users to modify data beyond their permitted role. This vulnerability is fixed in 16.9.1.
AnalysisAI
Privilege escalation in ERPNext versions prior to 16.9.1 allows authenticated low-privileged users to modify data outside their assigned role due to missing authorization checks on certain endpoints. The flaw carries a CVSS 9.9 score with scope change, but EPSS is only 0.04% and CISA SSVC reports no observed exploitation, indicating no public exploit identified at time of analysis. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Requires a valid authenticated session on the ERPNext instance (CVSS PR:L) - any account, including low-privilege portal/customer roles, appears sufficient since the flaw is missing authorization rather than missing authentication. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | Signals here conflict and need careful weighting. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker who registers or compromises a low-privilege ERPNext account (e.g., a customer or portal user) sends crafted requests directly to the vulnerable endpoints to modify records their role should not be able to touch, such as elevating their own permissions, altering financial documents, or tampering with master data. Because the scope is changed and integrity impact is high, this single foothold can pivot into full administrative control of the ERP instance. … |
| Remediation | Upgrade to the vendor-released patch ERPNext 16.9.1 or later as described in https://github.com/frappe/erpnext/security/advisories/GHSA-cg5w-7g26-p3w9; this is the primary and only confirmed fix. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: Inventory all ERPNext instances and identify those running versions prior to 16.9.1; restrict administrative access to essential personnel. …
