{"apiVersion":"1.0","identifier":"CVE-2026-76905","description":"kin-openapi is a Go project for handling OpenAPI files. 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.","publishedAt":"2026-08-21T21:17:06","lastModifiedAt":"2026-08-25T15:16:42","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-76905","cvssScore":7.5,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","epssProbability":0.00354,"riskScore":0.77,"affectedProduct":"kin-openapi","affectedVersions":">=0.10.0,<0.141.0","vulnerabilityType":"Library","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-76905","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-76905","en":"https://www.redsauce.net/en/cves/CVE-2026-76905","fr":"https://www.redsauce.net/fr/cves/CVE-2026-76905","pt":"https://www.redsauce.net/pt/cves/CVE-2026-76905","de":"https://www.redsauce.net/de/cves/CVE-2026-76905","sk":"https://www.redsauce.net/sk/cves/CVE-2026-76905","el":"https://www.redsauce.net/el/cves/CVE-2026-76905"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-76905"}}
