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.","cvss_v4":null,"cvss_v3":{"version":"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},"cwes":["CWE-754"],"references":["https://github.com/getkin/kin-openapi/commit/4487f198ab8be0c37d6ca72c54f5dca4dc25270e","https://github.com/getkin/kin-openapi/releases/tag/v0.148.0","https://github.com/getkin/kin-openapi/security/advisories/GHSA-rj39-cv6w-8wv7","https://github.com/getkin/kin-openapi/security/advisories/GHSA-rj39-cv6w-8wv7"],"products":[],"source":"nvd","synced_at":"2026-10-21T03:56:58.798400159+00:00"},"epss":{"cve":"CVE-2026-100352","score":0.00595,"percentile":0.48133,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-rj39-cv6w-8wv7","url":"https://osv.dev/vulnerability/GHSA-rj39-cv6w-8wv7","summary":"kin-openapi: YAML NaN/Inf Values Bypass Built-in Guards and Panic via OAS 3.1 Validation Path","modified":"2026-10-15T20:30:11.872986933Z","packages":[{"ecosystem":"Go","name":"github.com/getkin/kin-openapi","purl":"pkg:golang/github.com/getkin/kin-openapi","ranges":["<0.148.0"],"fixed":["0.148.0"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
