SCA: security update for @orval/core (GHSA-h526-wf6g-67jv)

critical Tenable Self-Hosted Container Security Plugin ID 436835

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Orval generates type-safe JS clients (TypeScript) from any valid OpenAPI v3 or Swagger v2 specification.
 Versions prior to 7.19.0 until 8.0.2 are vulnerable to arbitrary code execution in environments consuming
 generated clients. This issue is similar in nature to CVE-2026-22785, but affects a different code path in
 @orval/core that was not addressed by CVE-2026-22785's fix. The vulnerability allows untrusted OpenAPI
 specifications to inject arbitrary TypeScript/JavaScript code into generated clients via the
 x-enumDescriptions field, which is embedded without proper escaping in getEnumImplementation(). I have
 confirmed that the injection occurs during const enum generation and results in executable code within the
 generated schema files. Orval 7.19.0 and 8.0.2 contain a fix for the issue. (CVE-2026-23947)
