CVE-2026-25141
Orval has Code Injection via unsanitized x-enum-descriptions using JS comments
Impact
[CVE-2026-23947](https://github.com/advisories/GHSA-h526-wf6g-67jv) had an incomplete fix While the current [jsStringEscape](https://github.com/orval-labs/orval/blob/02211fc413524be340ba9ace866a2ef68845ca7c/packages/core/src/utils/string.ts#L227) function properly handles single quotes ('), double quotes (") and other characters, it fails to sanitize * and / characters. This allows attackers to break out of JavaScript comment blocks using */ sequences and inject arbitrary code into generated files. **Example:** ```yaml openapi: 3.0.4 info: title: Enum PoC version: "1.0.0" paths: /ping: get: operationId: ping responses: "200": description: ok content: application/json: schema: $ref: "#/components/schemas/EvilEnum" components: schemas: EvilEnum: type: string
