Vulnerability from cvelistv5 – Published: 2026-09-11 14:22 – Updated: 2026-09-11 14:57

Title

NextGen Healthcare Mirth Connect Improper Restriction of XML External Entity Reference

Summary

When XML batch processing is turned on and the XPath option is selected, the raw batch input goes through a default XPath/JAXP setup with no entity restrictions, so XXE injection can allow data exfiltration and denial-of-service attacks.
