CVE-2025-30065 has been discovered in the Apache Parquet Java library, specifically within its parquet-avro module.
This flaw is categorized as Deserialization of Untrusted Data (CWE-502) and has been assigned the highest possible CVSS score of 10.0, indicating “Critical” severity.
The vulnerability poses a serious risk to systems that process Parquet files, particularly when those files originate from untrusted or external sources.
Impact of the Vulnerability
The flaw allows attackers to execute arbitrary code on systems that process maliciously crafted Parquet files.
Exploitation could lead to:
- System Takeover: Attackers could gain full control of the system.
- Data Breaches: Sensitive information may be stolen or altered.
- Malware Deployment: Ransomware, cryptominers, or other harmful software could be installed.
- Service Disruption: Systems may experience denial-of-service attacks or data corruption.
This vulnerability affects all versions of the Apache Parquet Java library up to and including 1.15.0. It was introduced in version 1.8.0, making any application using these versions potentially vulnerable.
Exploitation Status
As of April 2025, there are no known reports of active exploitation in the wild.
However, given the critical nature of this flaw and its public disclosure, attackers may soon develop exploits.
Organizations should act immediately to mitigate risks.
Mitigation Steps
To protect your systems, consider the following actions:
- Upgrade to Apache Parquet 1.15.1 or Later:
- The Apache Software Foundation has released version 1.15.1, which addresses this vulnerability.
- Avoid Processing Untrusted Files:
- Until patched, avoid importing Parquet files from unknown or unverified sources.
- Implement Input Validation:
- Scan file schemas for anomalies before processing.
- Enhance Monitoring:
- Enable logging and monitoring for unusual activities, such as unexpected processes or network connections during Parquet file processing.
- Stay Updated:
- Monitor advisories from Apache and cybersecurity authorities for further updates.
