{"id":"CVE-2026-24132","aliases":["GHSA-f456-rf33-4626"],"url":"https://o3.security/vulnerability/CVE-2026-24132","summary":"Orval Mock Generation Code Injection via const","details":"Orval generates type-safe JS clients (TypeScript) from any valid OpenAPI v3 or Swagger v2 specification. Versions \n7.19.0 and below and 8.0.0-rc.0 through 8.0.2 allow untrusted OpenAPI specifications to inject arbitrary TypeScript/JavaScript into generated mock files via the const keyword on schema properties. These const values are interpolated into the mock scalar generator (getMockScalar in packages/mock/src/faker/getters/scalar.ts) without proper escaping or type-safe serialization, which results in attacker-controlled code being emitted into both interface definitions and faker/MSW handlers. The vulnerability is similar in impact to the previously reported enum x-enumDescriptions (GHSA-h526-wf6g-67jv), but it affects a different code path in the faker-based mock generator rather than @orval/core. The issue has been fixed in versions 7.20.0 and 8.0.3.","published":"2026-01-22T23:47:45.846Z","modified":"2026-07-15T01:49:10.136366600Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"@orval/mock","fixedVersion":"7.20.0"},{"ecosystem":"npm","name":"@orval/mock","fixedVersion":"8.0.3"}],"fix":{"url":"https://github.com/orval-labs/orval/commit/44ca8c1f5f930a3e4cefb6b79b38bcde7f8532a5","label":"orval-labs/orval@44ca8c1"},"references":[{"type":"WEB","url":"https://github.com/orval-labs/orval/releases/tag/v7.20.0"},{"type":"WEB","url":"https://github.com/orval-labs/orval/releases/tag/v8.0.3"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/24xxx/CVE-2026-24132.json"},{"type":"ADVISORY","url":"https://github.com/orval-labs/orval/security/advisories/GHSA-f456-rf33-4626"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-24132"},{"type":"FIX","url":"https://github.com/orval-labs/orval/commit/44ca8c1f5f930a3e4cefb6b79b38bcde7f8532a5"},{"type":"FIX","url":"https://github.com/orval-labs/orval/commit/6d8ece07ccb80693ad43edabccb3957aceadcd06"},{"type":"FIX","url":"https://github.com/orval-labs/orval/commit/9b211cddc9f009f8a671e4ac5c6cb72cd8646b62"},{"type":"FIX","url":"https://github.com/orval-labs/orval/pull/2828"},{"type":"FIX","url":"https://github.com/orval-labs/orval/pull/2829"},{"type":"FIX","url":"https://github.com/orval-labs/orval/pull/2830"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-15T01:49:10.136366600Z"}}
