CVE-2026-72906 in ERPNext
Summary
by MITRE • 08/11/2026
ERPNext is a free and open source Enterprise Resource Planning tool. Prior to 15.111.0 and 16.22.0, the send_auto_email function in erpnext/accounts/doctype/process_statement_of_accounts/process_statement_of_accounts.py lacks a Process Statement Of Accounts permission check, allowing an authenticated low-privilege user to trigger automated emails outside the permitted role. This issue is fixed in versions 15.111.0 and 16.22.0.

Analysis

The vulnerability identified in ERPNext affects versions prior to 15.111.0 and 16.22.0 where the send_auto_email function in the process_statement_of_accounts.py file fails to implement proper permission validation. This flaw exists within the accounts module of the enterprise resource planning system, specifically in the automated email triggering mechanism that generates account statements. The function operates without verifying whether the authenticated user possesses the necessary privileges to initiate such communications, creating a path for privilege escalation through unauthorized email automation.
This security weakness represents a violation of the principle of least privilege and constitutes a direct breach of access control mechanisms within the application's permission architecture. The vulnerability allows low-privilege users to exploit the automated email functionality to send statements to arbitrary recipients, potentially exposing sensitive financial information to unauthorized parties. From a compliance perspective, this issue directly impacts data protection requirements under standards such as iso 27001 and gdpr where access controls must be strictly enforced to prevent unauthorized data exposure.
The technical implementation flaw stems from the absence of proper authorization checks within the send_auto_email function, which operates in the context of process statement of accounts functionality. This type of vulnerability typically falls under CWE-284 Access Control Issues, specifically related to insufficient authorization checks during automated processes. The lack of permission validation creates an attack surface where malicious actors with minimal privileges can leverage the system's legitimate email capabilities for unauthorized communication.
From an operational impact standpoint, this vulnerability enables potential data leakage through automated email distribution channels that should be restricted to authorized personnel only. The affected functionality could be exploited to send sensitive financial statements to external addresses, potentially leading to information disclosure and compliance violations. Attackers might use this weakness to conduct reconnaissance by sending test emails to various recipients or to distribute sensitive account information to unauthorized third parties.
The mitigation strategy involves implementing proper permission validation within the send_auto_email function to ensure that only users with appropriate Process Statement Of Accounts permissions can trigger automated email communications. This aligns with ATT&CK technique T1078 Valid Accounts, where attackers exploit legitimate accounts to perform unauthorized actions. Organizations should also implement monitoring controls to detect unusual email sending patterns and establish proper role-based access controls within the ERPNext system. The fix implemented in versions 15.111.0 and 16.22.0 addresses this issue by incorporating mandatory permission checks before allowing automated email processing.
