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. This issue is fixed in version 1.29.1 and 1.32.5.","state":0,"publishedAt":"2026-07-16T14:42:02.337+00:00","modifiedAt":"2026-08-17T15:02:40.475+00:00","affected":[{"ecosystem":"Vendor product","name":"kiota","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"microsoft\",\n                    \"product\": \"kiota\",\n                    \"versions\": [\n                        {\n                            \"version\": \">= 1.30.0, < 1.31.1\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"< 1.29.1\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:L/VI:H/VA:L/SC:N/SI:N/SA:N","score":7,"severity":"HIGH"}],"references":["https://github.com/microsoft/kiota/security/advisories/GHSA-4rj6-vrwv-wr8m","https://github.com/microsoft/kiota/pull/7885","https://github.com/microsoft/kiota/commit/4049327872db7846ace35c9003774d3e3878e4e9","https://github.com/microsoft/kiota/releases/tag/v1.32.5"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-59863","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-59863","identifiers":["CVE-2026-59863"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
