CyberRota Analysis
AI-GeneratedHAPI FHIR versions prior to 6.9.11 are vulnerable to a StackOverflowError due to the lack of a maximum element nesting depth in the XhtmlParser.java, allowing attackers to exploit deeply nested narratives in FHIR resources. This can lead to denial-of-service conditions by crashing parsing or validation worker threads, impacting any application that processes attacker-supplied FHIR JSON or XML. Organizations using HAPI FHIR for healthcare interoperability should prioritize upgrading to version 6.9.11 to mitigate this high-severity vulnerability.

Original NVD Description
HAPI FHIR is a complete implementation of the HL7 FHIR standard for healthcare interoperability in Java. Prior to 6.9.11, XhtmlParser.java imposes no maximum element nesting depth, so a deeply nested text.div narrative triggers unbounded recursion between parseElementInner() and parseElement(), raising a StackOverflowError. An attacker who can submit FHIR resources containing such narratives can thus crash a parsing or validation worker thread, affecting validator services and any application that parses attacker-supplied FHIR JSON or XML. This issue is fixed in version 6.9.11.
