From 0.136.0 until 0.143.0, openapi3filter accepts OpenAPI 3.1 array schemas without an items keyword and then dereferences the nil Schema.Items value while decoding application/x-www-form-urlencoded or multipart/form-data request bodies, response headers, and other array parameter surfaces. A remote unauthenticated client can reach an affected operation with a nonempty request or matching response and deterministically trigger a nil-pointer panic during ValidateRequest or ValidateResponse. OpenAPI 3.0 documents are not affected because document validation rejects arrays without items, and JSON request bodies use a different decoder path. This issue is fixed in version 0.143.0.","state":0,"publishedAt":"2026-10-15T15:29:05.238+00:00","modifiedAt":"2026-10-20T02:45:09.805+00:00","affected":[{"ecosystem":"Vendor product","name":"kin-openapi","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"getkin\",\n                    \"product\": \"kin-openapi\",\n                    \"versions\": [\n                        {\n                            \"version\": \">= 0.136.0, < 0.143.0\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5,"severity":"HIGH"}],"references":["https://github.com/getkin/kin-openapi/security/advisories/GHSA-p6wj-qrr4-pgh5","https://github.com/getkin/kin-openapi/commit/30e292371a89ca6d1f91a9553e0aa518b49f838d","https://github.com/getkin/kin-openapi/releases/tag/v0.143.0"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-97394","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-97394","identifiers":["CVE-2026-97394"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
