CVE-2026-84364 Hono: Unbounded dot-notation nesting in `parseBody()` can cause memory exhaustion

Hono is a Web application framework that provides support for any JavaScript runtime. Prior to 4.13.5, when parseBody expands dot-separated form field names into nested objects with dot-notation parsing enabled, it does not limit the nesting depth or the total number of intermediate objects...

CVE-2026-62295

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-2026-62296

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, raisi...
