Full technical detail▾

Overview

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.

Remediation

Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
