CVE-2026-81876

NVD: HAPI FHIR is a complete implementation of the HL7 FHIR standard for healthcare interoperability in Java. NVD: SHCParser.decodeJWT() reaches SHCParser.inflate(), where Inflater.inflate() can return zero while Inflater.finished() remains false and Inflater.needsInput() is true. NVD: The loop also lacks an Inflater.needsDictionary() termination check, SHCParser.decompress() contains the same zero-progress pattern, and ResourceChecker.java can reach SHC parsing during file-format detection.
