Financial Report Template Method Injection in Frappe ERPNext

Publication date: 2026-09-23

Last updated on: 2026-09-23

Assigner: VulnCheck

Description
Frappe ERPNext versions before 16.34.1 fail to validate that Financial Report Template calculation_formula values reference whitelisted methods before passing them to frappe.call(). Accounts Managers can supply arbitrary dotted Python paths to invoke non-whitelisted internal server-side methods and read their return values.

Executive Summary

This vulnerability affects Frappe ERPNext versions before 16.34.1. It involves insufficient validation of Financial Report Template calculation_formula values. Accounts Managers can supply arbitrary Python paths that are passed to frappe.call() without whitelisting, allowing invocation of non-whitelisted internal server-side methods and reading their return values.

Detection Guidance

Check ERPNext version with: bench version. If version is below 16.34.1, the system is vulnerable. Inspect financial report templates for suspicious calculation_formula values containing arbitrary Python paths or non-whitelisted methods.

Impact Analysis

An attacker with Accounts Manager access could exploit this to read sensitive data, manipulate financial reports, or execute unauthorized internal methods. This may lead to data breaches, financial misreporting, or potential remote code execution depending on the methods invoked.

Compliance Impact

This vulnerability could lead to unauthorized data exposure or manipulation, violating GDPR's data integrity and confidentiality requirements and HIPAA's safeguards for protected health information. Non-compliance risks include legal penalties, reputational damage, and loss of trust.

Mitigation Strategies

Upgrade ERPNext to version 16.34.1 or later immediately. Review and remove any unauthorized financial report templates with suspicious calculation_formula values. Restrict Accounts Manager role permissions to prevent template modifications.
