CVE-2025-30065Public exploitNetwork attack vector

Code execution via untrusted Avro class instantiation

Published Apr 1, 2025 · Updated Feb 26, 2026

Unsafe deserialization in Apache Parquet Java 1.15.0 and earlier allows remote attackers to execute code through crafted Parquet files. The parquet-avro AvroConverters path trusts a schema field's java-class property, loads the named class, and invokes its String constructor during record conversion. Exploitation requires an application to ingest an attacker-controlled file with parquet-avro and a usable class with constructor side effects on its classpath.
