CVE-2026-33910
Published: 25 March 2026
Summary
CVE-2026-33910 is a high-severity SQL Injection (CWE-89) vulnerability in Open-Emr Openemr. Its CVSS base score is 7.2 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 34.1th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-2 (Flaw Remediation).
Deeper analysis
CVE-2026-33910 is a SQL injection vulnerability (CWE-89) affecting OpenEMR, a free and open source electronic health records and medical practice management application. The flaw resides in the patient selection feature due to insufficient input validation and impacts versions up to and including 8.0.0.2. Published on 2026-03-25, it carries a CVSS v3.1 base score of 7.2 (AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H).
Authenticated attackers with high privileges (PR:H) can exploit the vulnerability remotely over the network with low attack complexity and no user interaction required. Exploitation enables high-impact compromise of confidentiality, integrity, and availability, potentially allowing arbitrary SQL query execution against the backend database.
Mitigation is available in OpenEMR version 8.0.0.3, which includes a patch addressing the input validation issue. Security practitioners should review the fixing commit at https://github.com/openemr/openemr/commit/73db3264aed253684532839380cae3b0a56c83d2, the release notes at https://github.com/openemr/openemr/releases/tag/v8_0_0_3, and the GitHub security advisory at https://github.com/openemr/openemr/security/advisories/GHSA-x32c-xj5g-7jx7 for implementation details.
