Critical Security Flaws Expose Healthcare Data Through NextGen Mirth Connect Integration Platform
NextGen Healthcare's Mirth Connect integration platform versions 4.7.1 and earlier contain three critical vulnerabilities disclosed by CISA in September 2026. These include a SQL injection flaw (CVE-2026-82583) allowing authenticated users to execute arbitrary SQL commands through the Database Connector API, and two XML External Entity (XXE) injection vulnerabilities (CVE-2026-78224, CVE-2026-82578) in the XSLT Transformer and XML batch processing components. Successful exploitation could lead to credential disclosure, arbitrary file writes, data exfiltration, and denial-of-service conditions affecting healthcare data integration workflows. These vulnerabilities highlight the growing security risks in healthcare integration platforms as attackers increasingly target healthcare infrastructure. The disclosure comes amid heightened scrutiny of healthcare cybersecurity following recent high-profile attacks on medical systems and the critical role of data integration platforms in healthcare operations.
