Summary
Apache Parquet Avro Module Vulnerable to Arbitrary Code Execution
Schema parsing in the parquet-avro module of Apache Parquet 1.15.0 and previous versions allows bad actors to execute arbitrary code
Users are recommended to upgrade to version 1.15.1, which fixes the issue.
Impact
Untrusted serialized data is processed by a deserializer that can instantiate arbitrary objects or execute code as a side effect. Typical impact: arbitrary code execution or logic abuse.
Affected versions
Security releases
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-2025-30065? CVE-2025-30065 is a critical-severity insecure deserialization vulnerability in org.apache.parquet:parquet-avro (maven), affecting versions < 1.15.1. It is fixed in 1.15.1. Untrusted serialized data is processed by a deserializer that can instantiate arbitrary objects or execute code as a side effect.
- Which versions of org.apache.parquet:parquet-avro are affected by CVE-2025-30065? org.apache.parquet:parquet-avro (maven) versions < 1.15.1 is affected.
- Is there a fix for CVE-2025-30065? Yes. CVE-2025-30065 is fixed in 1.15.1. Upgrade to this version or later.
- Is CVE-2025-30065 exploitable, and should I be worried? Whether CVE-2025-30065 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-2025-30065 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.
- How do I fix CVE-2025-30065? Upgrade
org.apache.parquet:parquet-avroto 1.15.1 or later.
