CVE-2026-62295

HAPI FHIR (Java) prior to 6.9.11 has a denial-of-service risk: the JSON parser in org.hl7.fhir.utilities.json.parser.JsonParser enforces no maximum nesting depth, so deeply nested, valid FHIR JSON can trigger unbounded readArray/readObject recursion and cause a StackOverflowError before validatio...

CVE-2026-62295 HAPI FHIR: JSON utility parser unbounded recursion causes StackOverflow denial of service

HAPI FHIR is a complete implementation of the HL7 FHIR standard for healthcare interoperability in Java. Prior to 6.9.11, the JSON utility parser in org.hl7.fhir.utilities.json.parser.JsonParser enforces no maximum nesting depth for arrays or objects. As a result, a small but deeply nested,...

CVE-2026-68494

A flaw was found in jackson-core. A remote attacker can exploit an incomplete fix in the non-blocking JSON parser by streaming specially crafted JSON data in small chunks. This bypasses the intended number length constraint, causing the parser to accumulate excessive memory per connection. This...
