What is CVE-2025-46762?
CVE-2025-46762 is a high-severity unsafe deserialization vulnerability in Apache Parquet Java, published on 6 May 2025. An attacker needs administrator access to exploit it, and only if a user opens a file or follows a link.
Official description
Schema parsing in the parquet-avro module of Apache Parquet 1.15.0 and previous versions allows bad actors to execute arbitrary code.
While 1.15.1 introduced a fix to restrict untrusted packages, the default setting of trusted packages still allows malicious classes from these packages to be executed.
The exploit is only applicable if the client code of parquet-avro uses the "specific" or the "reflect" models deliberately for reading Parquet files. ("generic" model is not impacted)
Users are recommended to upgrade to 1.15.2 or set the system property "org.apache.parquet.avro.SERIALIZABLE_PACKAGES" to an empty string on 1.15.1. Both are sufficient to fix the issue.
Weakness: CWE-73
