In Apache Linkis <=1.3.1, due to the default token generated by Linkis Gateway deployment being too simple, it is easy for attackers to obtain the default token for the attack. Generation rules should add random values. We recommend users upgrade the version of Linkis to version 1.3.2 And modify the default token value. You can refer to Token authorization[1] https://linkis.apache.org/docs/latest/auth/token https://linkis.apache.org/docs/latest/auth/token

In Apache Linkis <=1.3.1, due to the Manager module engineConn material upload does not check the zip path, This is a Zip Slip issue, which will lead to a potential RCE vulnerability. We recommend users upgrade the version of Linkis to version 1.3.2.

In Apache Linkis <=1.3.1, The PublicService module uploads files without restrictions on the path to the uploaded files, and file types. We recommend users upgrade the version of Linkis to version 1.3.2.  For versions <=1.3.1, we suggest turning on the file path check switch in linkis.properties `wds.linkis.workspace.filesystem.owner.check=true` `wds.linkis.workspace.filesystem.path.check=true`

In Apache Linkis <=1.3.0 when used with the MySQL Connector/J, a deserialization vulnerability with possible remote code execution impact exists when an attacker has write access to a database and configures new datasource with a MySQL data source and malicious parameters. Therefore, the parameters in the jdbc url should be blacklisted. Versions of Apache Linkis <= 1.3.0 will be affected. We recommend users to upgrade the version of Linkis to version 1.3.1.

In Apache Linkis <=1.3.0 when used with the MySQL Connector/J in the data source module, an authenticated attacker could read arbitrary local files by connecting a rogue MySQL server, By adding allowLoadLocalInfile to true in the JDBC parameter. Therefore, the parameters in the JDBC URL should be blacklisted. Versions of Apache Linkis <= 1.3.0 will be affected.  We recommend users upgrade the version of Linkis to version 1.3.1

In Apache Linkis <=1.2.0 when used with the MySQL Connector/J, a deserialization vulnerability with possible remote code execution impact exists when an attacker has write access to a database and configures a JDBC EC with a MySQL data source and malicious parameters. Therefore, the parameters in the jdbc url should be blacklisted. Versions of Apache Linkis <= 1.2.0 will be affected, We recommend users to update to 1.3.0.
