Prior to version 6.9.12, SHCParser in org.hl7.fhir.r5\/src\/main\/java\/org\/hl7\/fhir\/r5\/elementmodel\/SHCParser.java can consume attacker-controlled Smart Health Card JWT content whose header contains zip: &#8220;DEF&#8221; and whose small raw-DEFLATE payload expands to a very large value. SHCParser.decodeJWT() passes the decoded payload to SHCParser.inflate(), which accumulates all decompressed bytes in a ByteArrayOutputStream without an output-size limit before JSON parsing, and SHCParser.decompress() contains the same unbounded pattern. An application or validator service that accepts attacker-supplied SHC content can therefore suffer excessive heap allocation, severe garbage-collection pressure, request failure, process instability, or process termination.
