Description

Code for IBM i is a Visual Studio Code extension for maintaining and compiling ILE languages on the IBMi platform. Prior to 3.0.1, src/ui/views/objectBrowser.ts stores Object Browser downloads and the edit-save flow content in the shared /tmp directory without reliable cleanup. On systems where /tmp is accessible to other local accounts, file contents remain readable after download or editing operations. This issue is fixed in version 3.0.1.
