A vulnerability.
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.

A vulnerability in Apache Linkis.
Problem Description
When using the JDBC engine and da
When using the JDBC engine and data source functionality, if the URL parameter configured on the frontend has undergone multiple rounds of URL encoding, it may bypass the system's checks. This bypass can trigger a vulnerability that allows unauthorized access to system files via JDBC parameters.
Scope of Impact
This issue affects Apache Linkis: from 1.3.0 through 1.7.0.
Severity level
moderate
Solution
Continuously check if the connection information contains the "%" character; if it does, perform URL decoding.
Users are recommended to upgrade to version 1.8.0, which fixes the issue.

In Apache Linkis <1.7.0, due to the lack of effective filtering
of parameters, an attacker configuring malicious Mysql JDBC parameters in the DataSource Manager Module will
allow the attacker to read arbitrary files from the Linkis server. Therefore, the parameters in the Mysql JDBC URL should be blacklisted. This attack requires the attacker to obtain an authorized account from Linkis before it can be carried out. Versions of Apache Linkis < 1.7.0 will be affected.
We recommend users upgrade the version of Linkis to version 1.7.0.
