Summary

  • Bump fastjson 1.2.83 -> 1.2.84. This fixes CVE-2026-16723
    (affects 1.2.68 to 1.2.83; fixed in 1.2.84 per the fastjson2 advisory).

  • Bump avro 1.9.0 -> 1.11.4 in sink-connector and sink-connector-lightweight.
    This fixes CVE-2024-47561 (affects Avro before 1.11.4).

  • Update THIRD_PARTY_NOTICES.md.

    Verified

    • mvn dependency:tree shows avro 1.11.4 in both modules and fastjson 1.2.84 in sink-connector.
    • mvn compile for sink-connector passes. SchemaOverrideConfigTest passes (2 tests).

    Notes

    • sink-connector-lightweight takes clickhouse-kafka-sink-connector:0.0.9 from Maven.
      A new release of that library is needed for shipped jars to change.
    • The only fastjson use is an unused import in SchemaOverrideConfig.java.
      The dependency could be removed in a later change.
    • I did not run the full test suite.

- fastjson 1.2.83 -> 1.2.84 (fixes CVE-2026-16723)
- avro 1.9.0 -> 1.11.4 in sink-connector and sink-connector-lightweight
  (fixes CVE-2024-47561)
- Update THIRD_PARTY_NOTICES.md for the new fastjson version
