HAPI FHIR versions prior to 6.9.12 contain an improper input validation vulnerability in the SHCParser component. This flaw can cause an infinite loop when processing specially crafted Smart Health Card JWTs with a 'zip' header set to 'DEF' and an empty or truncated raw-DEFLATE payload. The infinite loop can indefinitely pin a JVM worker thread, potentially exhausting all validation workers under concurrent requests. This issue is fixed in version 6.9.12.
