Impact
Jackson is shaded/relocated inside Apache Parquet's pre-built parquet-jackson bundle (to shaded/parquet/com/fasterxml/jackson/**), so Parquet references the relocated names and an unshaded Jackson can't be substituted. Raising fasterxml.jackson.version updates the standalone jackson jars Spark resolves (2.21.5 as of 4.2.0-r4) but can't rewrite classes already shaded into parquet-jackson. As of 2026-08-04 this cannot be fixed: Spark already overrides parquet.version to 1.17.1, the newest parquet-jackson on Maven Central (per https://repo.maven.apache.org/maven2/org/apache/parquet/parquet-jackson/maven-metadata.xml) — ahead of upstream Spark 4.2.0, which ships 1.17.0. The fix is Parquet 1.18.0: its rc1 tag sets jackson.version 2.22.1 (OSV reports no known vulns in jackson-core/databind 2.22.1), clearing all eleven findings on this component. But 1.18.0 is release-candidate only and 404s on Maven Central as of 2026-08-04. Action when it ships: bump parquet.version to 1.18.0 in enterprise-packages/spark-4.2/properties.yaml and rescan.
