Attack profile from CVSS 3.1 · CISA ADP. Fix status from CNA and GitHub. Impact type from CWE-434.
Summary
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`
