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.\nhttps://www.cve.org/CVERecord?id=CVE-2026-100352https://github.com/getkin/kin-openapi/security/advisories/GHSA-rj39-cv6w-8wv7https://github.com/getkin/kin-openapi/commit/4487f198ab8be0c37d6ca72c54f5dca4dc25270ehttps://github.com/getkin/kin-openapi/releases/tag/v0.148.0#getkin #kin-openapi#CVE_2026_100352#bot", "creation_timestamp": "2026-10-15T16:01:48.012002Z"}]}
