CVE-2025-59952 at a Glance
How to Fix CVE-2025-59952
To remediate this vulnerability, upgrade all affected Minio dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.
<dependency>
<groupId>io.minio</groupId>
<artifactId>minio</artifactId>
<version>8.6.0</version>
</dependency>Run the following command in your project directory to verify that all resolved dependencies use the patched release:
mvn dependency:tree -Dincludes=io.minioHow to Check if You Are Affected
To determine whether your Java application is affected by CVE-2025-59952, inspect your build dependencies using the Maven Dependency Plugin:
mvn dependency:tree -Dincludes=io.minioAnalyze the terminal output to locate any version of Minio in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 8.6.0), your application is affected.
Note: The mvn dependency:tree -Dincludes=io.minio command inspects the resolved dependency graph declared in your project's POM files; it does not perform automated security scanning or inspect runtime dynamic classpaths. Always verify runtime container classpaths and shaded JARs.
Technical Details
Vulnerability Mechanism & Technical Analysis
This vulnerability is classified under CWE-91: XML Injection (aka Blind XPath Injection), where the product does not properly neutralize special elements that are used in xml, allowing attackers to modify the syntax, content, or commands of the xml before it is processed by an end system. In Minio, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

"summary" : "MinIO Java Client XML Tag Value Substitution Vulnerability",
"details" : "#### Description\nIn minio-java versions prior to 8.6.0, XML tag values containing references to system properties or environment variables were automatically substituted with their actual values during processing. This unintended behavior could lead to the exposure of sensitive information, including credentials, file paths, or system configuration details, if such references were present in XML content from untrusted sources.\n\n#### Affected Versions\n- minio-java < 8.6.0\n\nAll applications utilizing affected versions of minio-java for parsing XML with potentially untrusted input are vulnerable.\n\n#### Impact\nThis vulnerability poses a high risk of information disclosure. Attackers could craft malicious XML inputs to extract sensitive data from the system's properties or environment variables, potentially compromising security in applications relying on minio-java for object storage operations.\n\n#### Patches\nThe issue is resolved in minio-java version 8.6.0 and later. In these versions, automatic substitution of XML tag values with system properties or environment variables has been disabled.\n\nUsers are strongly advised to upgrade to minio-java 8.6.0 or a newer release to mitigate the vulnerability.\n\n#### Workarounds\nNo full workarounds exist without upgrading the library. As interim measures:\n\n- Refrain from processing XML data from untrusted or external sources.\n- Implement input sanitization or validation to detect and remove references to \n system properties or environment variables in XML content.",
