{"id":"CVE-2026-100353","summary":"kin-openapi: Incomplete Fix for GHSA-p6wj-qrr4-pgh5: Three Unpatched nil-Items Panic Paths in openapi3filter","details":"kin-openapi is a Go project for handling OpenAPI files. 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.","aliases":["GHSA-vrcc-3ch7-hppw"],"modified":"2026-10-16T02:47:26.804347648Z","published":"2026-10-15T16:03:50.514Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/100xxx/CVE-2026-100353.json","cna_assigner":"GitHub_M","cwe_ids":["CWE-476"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/100xxx/CVE-2026-100353.json"},{"type":"FIX","url":"https://github.com/getkin/kin-openapi/commit/9814d1f2b212f3508bf52296aa9e248b2122a5a9"},{"type":"WEB","url":"https://github.com/getkin/kin-openapi/releases/tag/v0.149.0"},{"type":"ADVISORY","url":"https://github.com/getkin/kin-openapi/security/advisories/GHSA-vrcc-3ch7-hppw"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-100353"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/getkin/kin-openapi","events":[{"introduced":"ff4bce724cfa3fdf6fac4470c76a8511662b21f6"},{"fixed":"1a812b4b73ede7fa295c63a5c89d1ca7250dcc07"}],"database_specific":{"extracted_events":[{"introduced":"0.136.0"},{"fixed":"0.149.0"}],"source":"AFFECTED_FIELD"}}],"versions":["v0.148.0","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"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-100353.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"}]}
