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"
