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...

CVE-2026-62296

CVE-2026-62296 affects HAPI FHIR (Java). The vulnerable component is the XHTML parser (XhtmlParser.java) where, prior to 6.9.11, there is no maximum element nesting depth, allowing deeply nested text.div narratives to trigger unbounded recursion between parseElementInner() and parseElement(). Thi...

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-2026-62295

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-2026-65819 gopacket: Multiple layer decoders panic on crafted packets (out-of-bounds/underflow) enabling unauthenticated remote DoS via DecodingLayerParser

gopacket provides packet processing capabilities for Go. Through version 1.7.0, multiple layer decoders use attacker-controlled lengths, counts, or offsets before validating them against packet buffers, allowing a crafted packet decoded through DecodingLayerParser or DecodeFromBytes to trigger an...

CVE-2026-65819

CVE-2026-65819 affects gopacket before version 1.7.0, where multiple layer decoders may read attacker-controlled lengths, counts, or offsets before validating buffers. A crafted packet decoded via DecodingLayerParser or DecodeFromBytes can trigger an unrecovered panic, enabling unauthenticated re...

Ruby JSON: JSON::ResumableParser#partial_value dereferences a freed input buffer and crashes on truncated duplicate-key streams

Summary Ruby's JSON native C extension clears the consumed JSON::ResumableParser input buffer but leaves state.start, state.cursor, and state.end pointing into released storage. When partialvalue reconstructs an incomplete object containing duplicate keys, the duplicate-key warning path calls...
