{"apiVersion":"1.0","identifier":"CVE-2026-71864","description":"Orval generates type-safe JavaScript clients in TypeScript from OpenAPI v3 and Swagger v2 specifications. Prior to 8.21.0, a double quote in a header parameter name is emitted into the generated request-validation zod.object({...}) schema without safe encoding. This permits attacker-controlled JavaScript to be evaluated when the generated zod schema module is imported, resulting in code execution in the developer, CI, test, or application environment. The affected code is packages/zod/src/index.ts and header request-validation generation. This issue is fixed in version 8.21.0.","publishedAt":"2026-08-19T18:17:23","lastModifiedAt":"2026-08-25T03:16:56","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-71864","cvssScore":9.3,"cvssVector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","epssProbability":0.00478,"riskScore":0.97,"affectedProduct":"orval","affectedVersions":"<8.21.0","vulnerabilityType":"Library","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-71864","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-71864","en":"https://www.redsauce.net/en/cves/CVE-2026-71864","fr":"https://www.redsauce.net/fr/cves/CVE-2026-71864","pt":"https://www.redsauce.net/pt/cves/CVE-2026-71864","de":"https://www.redsauce.net/de/cves/CVE-2026-71864","sk":"https://www.redsauce.net/sk/cves/CVE-2026-71864","el":"https://www.redsauce.net/el/cves/CVE-2026-71864"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-71864"}}
