Prior to 13.12.2, src/schema-parser/base-schema-parsers/enum.ts passes components.schemas.*.enum[i] values to Ts.StringValue in src/configuration.ts without escaping before templates/base/enum-data-contract.ejs renders TypeScript enum declarations, allowing an attacker-controlled OpenAPI spec to inject code that executes when the generated module is imported. This issue is fixed in version 13.12.2.","published":"2026-07-29T14:32:41.168Z","modified":"2026-08-12T03:51:46.798381302Z","cvss":{"score":8.3,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:C/C:H/I:H/A:H"},"epss":{"score":0.0027,"percentile":0.19195,"asOf":"2026-09-12"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"swagger-typescript-api","fixedVersion":"13.12.2"}],"fix":{"url":"https://github.com/acacode/swagger-typescript-api/commit/306d59acb8ffbb00f953f807b97234b21f51d9de","label":"acacode/swagger-typescript-api@306d59a"},"references":[{"type":"WEB","url":"https://github.com/acacode/swagger-typescript-api/releases/tag/v13.12.2"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/54xxx/CVE-2026-54664.json"},{"type":"ADVISORY","url":"https://github.com/acacode/swagger-typescript-api/security/advisories/GHSA-5f94-x226-ccpm"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-54664"},{"type":"FIX","url":"https://github.com/acacode/swagger-typescript-api/commit/306d59acb8ffbb00f953f807b97234b21f51d9de"},{"type":"FIX","url":"https://github.com/acacode/swagger-typescript-api/pull/1779"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:46.798381302Z"}}
