A recent discovery by cybersecurity experts has revealed a critical flaw in Apache Parquet's Java Library, which poses a significant risk to systems that rely on this library for data processing and storage. Learn more about the vulnerability, its implications, and how to mitigate it.
Apache Parquet's Java Library has a critical flaw (CVE-2025-30065) rated at CVSS score of 10.0, indicating high severity and impact. The vulnerability allows attackers to execute arbitrary code on vulnerable systems by tampering with specially crafted Parquet files. The issue is related to a Deserialization of Untrusted Data flaw that enables remote code execution (RCE) on affected systems. Experts warn of potential risks including unauthorized access, data tampering, system compromise, and malware deployment. Users are advised to upgrade to Apache Parquet Java version 1.15.1 or later, implement input validation, and enable monitoring and logging.
A recent discovery by cybersecurity experts has revealed a critical flaw in Apache Parquet's Java Library, which poses a significant risk to systems that rely on this library for data processing and storage. The vulnerability, tracked as CVE-2025-30065, has been rated at a CVSS score of 10.0, indicating a high level of severity and potential impact.
According to the security advisory published by Endor Labs, the flaw is located in the parquet-avro module of Apache Parquet 1.15.0 and earlier versions. The vulnerability allows attackers to execute arbitrary code on vulnerable systems by tampering with specially crafted Parquet files. This issue has significant implications for big-data frameworks such as Hadoop, Spark, Flink, and custom applications that use Parquet.
The critical flaw is a Deserialization of Untrusted Data issue, which enables an attacker to inject malicious data into the library's schema parsing process. This allows attackers to gain remote code execution (RCE) on vulnerable systems, potentially leading to unauthorized access, data tampering, or even system compromise.
If an attacker tricks a vulnerable system into reading a specially crafted Parquet file, they can execute arbitrary commands or software on that system. In practice, this could enable attackers to:
* Take control of the system: Run any commands or software to gain full access and control.
* Steal or tamper with data: Access sensitive information, copy it, or modify it at will.
* Install malware: Deploy ransomware, cryptominers, or other malicious software to compromise the system further.
* Disrupt services: Shut down critical services or corrupt data, leading to denial of service and business downtime.
Experts warn that all confidentiality, integrity, and availability of affected systems are at risk due to this vulnerability. While there is currently no known active exploit for CVE-2025-30065, threat actors may attempt to take advantage of the issue now that it has been publicly disclosed.
To mitigate this risk, users are advised to upgrade Apache Parquet Java to version 1.15.1 or later. Alternatively, they can avoid importing Parquet files from untrusted sources and implement input validation. Enabling monitoring and logging can help detect suspicious behavior, while staying informed about updates from Apache or cybersecurity authorities is essential for minimizing exposure.
In light of this critical vulnerability, it is imperative that organizations and individuals taking advantage of Apache Parquet's Java Library ensure they have the latest version installed and take proactive measures to safeguard their systems against potential exploitation.
