Upstream maintainers must cut a Hadoop release with Avro 1.11.4+ to resolve this CVE. The vulnerability is in jackson-core 2.12.7 bundled within hadoop-client-runtime-3.4.1.jar. Spark PR #40933 (SPARK-43263) attempted to upgrade Jackson to 2.15.0 but encountered dependency conflicts with Avro 1.11.1 which still pulls Jackson 2.12.7. The PR discussion confirmed that Avro must be upgraded first, which requires a new Hadoop release. CVE-2025-52999 is fixed in Jackson 2.15.0+.
