Prior to 1.29.1 and 1.32.5, Kiota honored a poisoned .kiota/workspace.json workspace configuration without validating per-client or per-plugin outputPath values during kiota client generate and kiota plugin generate, allowing a malicious repository or pull request to use absolute paths, rooted POSIX / paths, UNC \\\\ or // paths, Windows drive X:\\ paths, or .. traversal segments to write generated client files outside the workspace root on a developer or CI host.
