From 0.2.0 until 0.144.0, openapi3filter.ValidateRequest can encounter a NULL-pointer-dereference denial of service when an operation declares a content parameter whose application/json media type has no schema. In openapi3filter/req_resp_decoder.go, the default defaultContentParameterDecoder dereferences mt.Schema.Value without checking whether mt.Schema is nil, even though doc.Validate() accepts the document under OpenAPI 3.0.x and 3.1.x. A single unauthenticated request supplying the parameter value can panic request validation, causing an aborted request with log growth in the common synchronous net/http path or a full process crash in integrations without recovery. This issue is fixed in version 0.144.0.","state":0,"publishedAt":"2026-08-18T18:19:33.46+00:00","modifiedAt":"2026-10-22T22:10:00.25+00:00","affected":[],"metrics":[{"system":"CVSS 3.1 · security-advisories@github.com · Secondary","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","score":5.3,"severity":"MEDIUM"}],"references":["https://github.com/getkin/kin-openapi/commit/68ac2affa325514d7d6e731204d6a1edf6bdff64","https://github.com/getkin/kin-openapi/releases/tag/v0.144.0","https://github.com/getkin/kin-openapi/security/advisories/GHSA-jpcw-4wr7-c3vq"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-73502","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Deferred","weaknesses":["CWE-476"],"productCriteria":[],"sourceDates":{"published":"2026-08-18T18:19:33.460","lastModified":"2026-10-22T22:10:00.250"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
