CVE-2025-58439 is a high-severity SQL Injection vulnerability affecting the open-source Enterprise Resource Planning (ERP) software ERPNext, developed by the Frappe framework. The vulnerability exists in versions prior to 14.89.2 and from 15.0.0 up to 15.75.1. It arises due to improper neutralization of special elements in SQL commands (CWE-89), specifically a lack of validation or sanitization of input parameters in certain API endpoints. This flaw allows an attacker with at least low-level privileges (PR:L) to craft malicious input that can manipulate backend SQL queries, leading to error-based SQL Injection. Through this, attackers can extract sensitive information such as version details and potentially other confidential data from the database. The vulnerability does not require user interaction and can be exploited remotely over the network (AV:N) with low attack complexity (AC:L). The impact affects confidentiality and integrity but not availability, as the CVSS vector indicates no impact on availability. The issue has been addressed in ERPNext versions 14.89.2 and 15.76.0. No known exploits have been reported in the wild yet, but the high CVSS score of 8.1 underscores the criticality of timely patching. Given ERPNext’s role in managing enterprise resources, financial data, and operational workflows, exploitation could lead to significant data breaches and unauthorized data manipulation.

For European organizations using ERPNext, this vulnerability poses a significant risk to the confidentiality and integrity of sensitive business data, including financial records, customer information, and operational details. Successful exploitation could lead to unauthorized data disclosure, potentially violating GDPR and other data protection regulations, resulting in legal and financial penalties. The integrity compromise could disrupt business processes by allowing attackers to alter data, leading to operational inefficiencies or fraudulent activities. Since ERPNext is often used by SMEs and larger enterprises across Europe for critical business functions, the impact could be widespread. Additionally, the lack of known exploits currently does not preclude future attacks, especially as threat actors often target ERP systems due to their rich data stores and central role in business operations.

European organizations should immediately verify their ERPNext version and upgrade to 14.89.2 or 15.76.0 or later to remediate the vulnerability. Beyond patching, organizations should implement strict input validation and parameter sanitization on all endpoints, especially those exposed externally. Employing Web Application Firewalls (WAFs) with SQL Injection detection rules can provide an additional layer of defense. Conduct thorough code reviews and penetration testing focused on injection flaws in custom ERPNext extensions or integrations. Restrict ERPNext access to trusted networks and enforce the principle of least privilege for user accounts to minimize the risk of exploitation by low-privilege attackers. Regularly monitor logs for unusual query errors or suspicious activities indicative of attempted SQL Injection. Finally, ensure that backups are current and tested to enable recovery in case of data integrity compromise.
