From 0.10.0 until 0.141.0, openapi3filter.convertParseError in openapi3filter/validation_error_encoder.go dereferences e.Parameter.In without checking whether e.Parameter is nil. A malformed non-string scalar field in a multipart/form-data request body produces a nested ParseError with a nil RequestError.Parameter, and applications that render the validation error through openapi3filter.ConvertErrors or ValidationErrorEncoder panic. An unauthenticated client can repeatedly send such requests to deny service when the application lacks a recovery boundary. JSON request bodies and applications that do not use these error-rendering helpers are not affected. This issue is fixed in version 0.141.0.","state":0,"publishedAt":"2026-08-21T20:43:07.066+00:00","modifiedAt":"2026-08-25T14:21:42.702+00:00","affected":[{"ecosystem":"Vendor product","name":"kin-openapi","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"getkin\",\n                    \"product\": \"kin-openapi\",\n                    \"versions\": [\n                        {\n                            \"version\": \">= 0.10.0, < 0.141.0\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 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,"severity":"HIGH"}],"references":["https://github.com/getkin/kin-openapi/security/advisories/GHSA-mmfr-pmjx-hw9w","https://github.com/getkin/kin-openapi/commit/1d0a337c9b1570fab283be8a04c8af6e43b9a22c","https://github.com/getkin/kin-openapi/releases/tag/v0.141.0"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-76905","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-76905","identifiers":["CVE-2026-76905"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
