Description
Frappe ERPNext before 15.108.0 and 16.x before 16.18.0 contains a missing authorization vulnerability in certain endpoints that fail to enforce proper permission checks. Authenticated low-privileged users can call these endpoints to deactivate master records, modifying data beyond their permitted role.

Score: 5.3 Medium
EPSS: < 1% Very Low
KEV: No
Impact: Privilege Escalation with Data Deletion
Action: Immediate Patch
AI Analysis

Impact

The vulnerability allows an authenticated user with low‑privileged roles to deactivate master records through certain endpoints that fail to perform proper permission checks. Because the attack can lead to removal or inactivation of critical business data, it threatens the integrity of the system, potentially disrupting business processes and eroding data trust. The weakness is a classic example of missing authorization, classified under CWE‑862.

Affected Systems

The flaw exists in Frappe ERPNext deployments running versions earlier than 15.108.0 and in the 16.x branch before 16.18.0. Any installation of these versions that exposes the affected endpoints to users with standard privileges is at risk.

Risk and Exploitability

With a CVSS score of 5.3, the vulnerability is considered moderate in severity. The EPSS score is not available, and the issue is not listed in the CISA KEV catalog, suggesting that no mass exploitation campaign is currently underway. Attackers would need valid credentials and access to the system, but the missing authorization check lowers the barrier for a low‑privileged user to perform the exploit.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Upgrade Frappe ERPNext to version 15.108.0 or newer, or 16.18.0 or newer in the 16.x branch to apply the vendor patch.
  • Review role‑based access control settings and ensure that only authorized user roles possess the capability to deactivate master records.
  • Monitor audit logs for unexpected deactivation activity and consider restricting the deactivation endpoint to high‑privilege roles as a temporary safeguard.
