SQL Injection Vulnerabilities in OpenEMR Before 8.5.0

Publication date: 2026-11-13

Last updated on: 2026-11-13

Assigner: VulnCheck

Description
OpenEMR before 8.5.0 contains multiple sql injection vulnerabilities that allow authenticated users to inject payloads through ERA CLP01, form_facility, form_icd_codes, and POST key names. Attackers can perform UNION, blind, and error-based injection to read users_secure password hashes and patient PHI, and overwrite patient_data fields.

CWE ID Description
CWE-89 The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.

Executive Summary

CVE-2026-126463 is a SQL injection vulnerability in OpenEMR versions before 8.5.0. It allows authenticated attackers to inject malicious SQL commands through input fields like ERA CLP01, form_facility, form_icd_codes, and POST parameters. The flaw occurs because user input is directly concatenated into SQL queries instead of using safer parameterized queries.

Detection Guidance

To detect SQL injection vulnerabilities in OpenEMR, inspect HTTP requests for suspicious parameters like ERA CLP01, form_facility, form_icd_codes, or POST keys. Use tools like SQLmap to test for injection points with payloads such as ' OR 1=1 -- or ' UNION SELECT. Check server logs for unusual SQL errors or patterns.

Impact Analysis

Attackers can exploit this to read sensitive data such as password hashes, patient PHI including SSNs, OAuth tokens, and portal credentials. They may also modify patient data in some cases. Exploitation requires an authenticated session, with some variants needing specific roles or lacking CSRF protection.

Compliance Impact

This vulnerability could lead to unauthorized access and exposure of protected health information (PHI), which directly violates HIPAA requirements for safeguarding patient data. GDPR compliance may also be impacted due to unauthorized processing of personal data.

Mitigation Strategies

Upgrade OpenEMR to version 8.5.0 or later immediately. Ensure all user inputs are parameterized in SQL queries. Validate input fields against allow-lists and implement CSRF protection. Review and restrict database user permissions to limit data exposure.
