Prior to 0.148.0, the OpenAPI 3.1 validation path passes YAML NaN and infinity numeric values to santhosh-tekuri/jsonschema v6.0.2 without applying kin-openapi's existing finite-number guards. A remote unauthenticated client can send an application/yaml or application/x-yaml request body containing .nan, .inf, or -.inf to an operation with a numeric constraint, causing the dependency to create and dereference a nil big.Rat during ValidateRequest. Standard net/http servers recover the panic per connection, while other hosts or application goroutines may terminate the process. This issue is fixed in version 0.148.0.","state":0,"publishedAt":"2026-10-15T15:54:25.834+00:00","modifiedAt":"2026-10-20T02:46:20.849+00:00","affected":[{"ecosystem":"Vendor product","name":"kin-openapi","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"getkin\",\n                    \"product\": \"kin-openapi\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 0.148.0\",\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-rj39-cv6w-8wv7","https://github.com/getkin/kin-openapi/commit/4487f198ab8be0c37d6ca72c54f5dca4dc25270e","https://github.com/getkin/kin-openapi/releases/tag/v0.148.0"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-100352","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-100352","identifiers":["CVE-2026-100352"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
