{"id":"CVE-2026-100352","summary":"kin-openapi: YAML NaN/Inf Values Bypass Built-in Guards and Panic via OAS 3.1 Validation Path","details":"kin-openapi is a Go project for handling OpenAPI files. 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.","aliases":["GHSA-rj39-cv6w-8wv7"],"modified":"2026-10-16T02:47:26.800549404Z","published":"2026-10-15T15:54:25.834Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/100xxx/CVE-2026-100352.json","cna_assigner":"GitHub_M","cwe_ids":["CWE-754"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/100xxx/CVE-2026-100352.json"},{"type":"FIX","url":"https://github.com/getkin/kin-openapi/commit/4487f198ab8be0c37d6ca72c54f5dca4dc25270e"},{"type":"WEB","url":"https://github.com/getkin/kin-openapi/releases/tag/v0.148.0"},{"type":"ADVISORY","url":"https://github.com/getkin/kin-openapi/security/advisories/GHSA-rj39-cv6w-8wv7"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-100352"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/getkin/kin-openapi","events":[{"introduced":"0"},{"fixed":"4487f198ab8be0c37d6ca72c54f5dca4dc25270e"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"0.148.0"}],"source":"AFFECTED_FIELD"}}],"versions":["v0.147.0","v0.146.0","v0.145.0","v0.144.0","v0.143.0","v0.142.0","v0.141.0","v0.140.0","v0.139.0","v0.138.0","v0.137.0","v0.136.0","v0.135.0","v0.134.0","v0.133.0","v0.132.0","v0.131.0","v0.130.0","v0.129.0","v0.128.0","v0.127.0","v0.126.0","v0.125.0","v0.124.0","v0.123.0","v0.122.0","v0.121.0","v0.120.0","v0.119.0","v0.118.0","v0.117.0","v0.116.0","v0.115.0","v0.114.0","v0.113.0","v0.112.0","v0.111.0","v0.110.0","v0.109.0","v0.108.0","v0.107.0","v0.106.0","v0.105.0","v0.104.0","v0.103.0","v0.102.0","v0.101.0","v0.100.0","v0.99.0","v0.98.0","v0.97.0","v0.96.0","v0.95.0","v0.94.0","v0.93.0","v0.92.0","v0.91.0","v0.90.0","v0.89.0","v0.88.0","v0.87.0","v0.86.0","v0.85.0","v0.84.0","v0.83.0","v0.82.0","v0.81.0","v0.80.0","v0.79.0","v0.78.0","v0.77.0","v0.76.0","v0.75.0","v0.74.0","v0.73.0","v0.72.0","v0.71.0","v0.70.0","v0.69.0","v0.68.0","v0.67.0","v0.66.0","v0.65.0","v0.64.0","v0.63.0","v0.62.0","v0.61.0","v0.60.0","v0.59.0","v0.58.0","v0.57.0","v0.56.0","v0.55.0","v0.54.0","v0.53.0","v0.52.0","v0.51.0","v0.50.0","v0.49.0","v0.48.0","v0.47.0","v0.46.0","v0.45.1","v0.45.0","v0.44.0","v0.43.0","v0.42.0","v0.41.0","v0.40.0","v0.39.0","v0.38.0","v0.37.0","v0.36.0","v0.35.0","v0.34.0","v0.33.0","v0.32.0","v0.31.0","v0.30.0","v0.29.0","v0.28.0","v0.27.0","v0.26.0","v0.25.0","v0.24.0","v0.23.0","v0.22.1","v0.22.0","v0.21.0","v0.20.0","v0.19.0","v0.18.0","v0.17.0","v0.16.0","v0.15.0","v0.14.0","v0.13.0","v0.12.0","v0.11.0","v0.10.0","v0.9.0","v0.8.0","v0.7.0","v0.6.0","v0.5.1","v0.5.0","v0.4.0","v0.3.1","v0.3.0","v0.2.0","v0.1.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-100352.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
