Detailsinfo

A vulnerability was found in OpenEMR up to 8.4.x. It has been rated as critical. This issue affects an unknown functionality of the component Patient Portal. The manipulation of the argument _BitwiseAnd with an unknown input leads to a sql injection vulnerability. Using CWE to declare the problem leads to 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. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

OpenEMR before 8.5.0 contains an SQL injection vulnerability in the patient portal OnsiteDocument.Query endpoint, where mass-assigned _BitwiseAnd criteria parameters are placed unquoted into SQL with only quote-character escaping. Authenticated portal patients can inject SQL outside their per-patient scope to read the entire database, including other patients' demographics and users_secure password hashes.

The advisory is shared at github.com. The identification of this vulnerability is CVE-2026-126488 since 11/10/2026. The exploitation is known to be easy. The attack may be initiated remotely.
