Alert meAnalysisAIv1 – Mar 12, 2026
SQL injection in OpenEMR's Immunization module prior to version 8.0.0 enables authenticated users to execute arbitrary database queries through unparameterized patient_id inputs. This allows attackers to exfiltrate protected health information, steal credentials, and potentially achieve remote code execution with complete database compromise. Public exploit code exists for this vulnerability; organizations should upgrade to version 8.0.0 immediately.

3DescriptionGitHub Advisory
OpenEMR is a free and open source electronic health records and medical practice management application. Prior to version 8.0.0, an SQL injection vulnerability in the Immunization module allows any authenticated user to execute arbitrary SQL queries, leading to complete database compromise, PHI exfiltration, credential theft, and potential remote code execution. The vulnerability exists because user-supplied patient_id values are directly concatenated into SQL WHERE clauses without parameterization or escaping. Version 8.0.0 patches the issue.
Executive ViewAI
OpenEMR installations are vulnerable to a high-severity attack that could allow unauthorized access to sensitive patient health records and practice data. Organizations using OpenEMR must prioritize patching immediately, as public exploits are available and this directly impacts HIPAA compliance and patient privacy obligations.
Apply vendor patch. If immediate patching is not possible: implement network segmentation to restrict OpenEMR access to authorized users only, enable Web Application Firewall (WAF) rules to block known exploit patterns, enforce multi-factor authentication for all user access, and increase monitoring and logging of OpenEMR database and API access.

Attack Technique
SQL injection exploits the way applications construct database queries by mixing user input directly into SQL statements.
Remote Code Execution represents the critical moment when an attacker successfully runs arbitrary code on a target system without physical access.
