CVE-2025-46762Network attack vector

Arbitrary code execution via trusted package class instantiation

Published May 6, 2025 · Updated Feb 26, 2026

Code execution in Apache Parquet Java before 1.15.2 allows attackers to run arbitrary code through crafted Parquet file metadata. The parquet-avro AvroConverters path accepts java-class and java-key-class names from the embedded Avro schema, loads a class from the default trusted-package list, and invokes its public String constructor. Exposure requires an application to ingest attacker-controlled Parquet files with the specific or reflect reader model; the generic model is unaffected.
