Prior to 0.149.0, runtime request, response, and direct schema validation lacks cycle detection when an allOf, anyOf, or oneOf chain refers back to an ancestor schema, even though loading and document validation accept the circular reference. A request or response that reaches the affected schema causes unbounded recursion in Schema.visitJSON or openapi3filter.decodeValue and exhausts the Go goroutine stack. The resulting fatal stack overflow cannot be caught with recover and terminates the entire process, including unrelated requests. This issue is fixed in version 0.149.0.","state":0,"publishedAt":"2026-10-15T17:17:07.78+00:00","modifiedAt":"2026-10-15T19:17:12.943+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:H","score":7.5,"severity":"HIGH"}],"references":["https://github.com/getkin/kin-openapi/commit/9245cef66c840e27a08409a8a5cd0ee930c5bcff","https://github.com/getkin/kin-openapi/releases/tag/v0.149.0","https://github.com/getkin/kin-openapi/security/advisories/GHSA-g8cf-rcjf-c8cf"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-100354","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Deferred","weaknesses":["CWE-674"],"productCriteria":[],"sourceDates":{"published":"2026-10-15T17:17:07.780","lastModified":"2026-10-15T19:17:12.943"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
