Summary
Apache Parquet Java: Potential malicious code execution from trusted packages in the parquet-avro module when reading an Avro schema from a Parquet file metadata
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.

Kodem intelligence
Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.
Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.

Frequently Asked Questions
- What is CVE-2025-46762? CVE-2025-46762 is a high-severity security vulnerability in org.apache.parquet:parquet-avro (maven), affecting versions < 1.15.2. It is fixed in 1.15.2.
- Which versions of org.apache.parquet:parquet-avro are affected by CVE-2025-46762? org.apache.parquet:parquet-avro (maven) versions < 1.15.2 is affected.
- Is there a fix for CVE-2025-46762? Yes. CVE-2025-46762 is fixed in 1.15.2. Upgrade to this version or later.
- Is CVE-2025-46762 exploitable, and should I be worried? Whether CVE-2025-46762 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

- What actually determines whether CVE-2025-46762 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
