From 0.136.0 until 0.149.0, three openapi3filter decoder paths that were missed by the fix for GHSA-p6wj-qrr4-pgh5 lack a nil-items guard for legal OpenAPI 3.1 array schemas. An unauthenticated remote client can trigger a deterministic nil-pointer panic through an array query parameter, a deepObject query parameter containing an array property, or an application/x-www-form-urlencoded request body whose array property appears inside an allOf, anyOf, or oneOf subschema. The query and composed-body paths reach urlValuesDecoder.parseArray, while the deepObject path reaches buildResObj, and all pass a nil items schema into code that dereferences it. This issue is fixed in version 0.149.0.","state":0,"publishedAt":"2026-10-15T16:03:50.514+00:00","modifiedAt":"2026-10-15T16:03:50.514+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, < 0.149.0\",\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-vrcc-3ch7-hppw","https://github.com/getkin/kin-openapi/commit/9814d1f2b212f3508bf52296aa9e248b2122a5a9","https://github.com/getkin/kin-openapi/releases/tag/v0.149.0"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-100353","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-100353","identifiers":["CVE-2026-100353"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
