DescriptionCVE.org

Kiota is an OpenAPI based HTTP Client code generator. Prior to 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. This issue is fixed in version 1.32.5.

AnalysisAI

Arbitrary file write via path traversal in Microsoft Kiota (OpenAPI HTTP client/plugin code generator) before 1.32.5 allows a malicious repository or pull request to place files outside the workspace root on a developer or CI host. The tool trusts the checked-in .kiota/workspace.json and honors attacker-controlled per-client and per-plugin outputPath values during 'kiota client generate' and 'kiota plugin generate' without validating them. …
