Summary
When org.apache.linkis.metadata.util.HiveUtils.decode() fails to perform Base64 decoding, it records the complete input parameter string in the log via logger.error(str + "decode failed", e). If the input parameter contains sensitive information such as Hive Metastore keys, plaintext passwords will be left in the log files when decoding fails, resulting in information leakage.
Affected Scope
Component: Sensitive fields in hive-site.xml (e.g., javax.jdo.option.ConnectionPassword) or other fields encoded in Base64.
Version: Apache Linkis 1.0.0 – 1.7.0
Trigger Conditions
The value of the configuration item is an invalid Base64 string.
Log files are readable by users other than hive-site.xml administrators.
Severity: Low
The probability of Base64 decoding failure is low.
The leakage is only triggered when logs at the Error level are exposed.
Remediation
Apache Linkis 1.8.0 and later versions have replaced the log with desensitized content.
logger.error("URL decode failed: {}", e.getMessage()); // 不再输出 str
Users are recommended to upgrade to version 1.8.0, which fixes the issue.
Impact
CVE-2025-59355 has a CVSS score of 6.5 (Medium). The vector is network-reachable, low privileges required, and no user interaction. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. A fixed version is available (1.8.0); upgrading removes the vulnerable code path.

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-2025-59355? CVE-2025-59355 is a medium-severity security vulnerability in org.apache.linkis:linkis-metadata (maven), affecting versions >= 1.0.0, < 1.8.0. It is fixed in 1.8.0.
- How severe is CVE-2025-59355? CVE-2025-59355 has a CVSS score of 6.5 (Medium). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.
- Which versions of org.apache.linkis:linkis-metadata are affected by CVE-2025-59355? org.apache.linkis:linkis-metadata (maven) versions >= 1.0.0, < 1.8.0 is affected.
- Is there a fix for CVE-2025-59355? Yes. CVE-2025-59355 is fixed in 1.8.0. Upgrade to this version or later.
- Is CVE-2025-59355 exploitable, and should I be worried? Whether CVE-2025-59355 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-2025-59355 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-2025-59355? Upgrade
org.apache.linkis:linkis-metadatato 1.8.0 or later.
