SCA: security update for @hey-api/openapi-ts (GHSA-hhx9-57xq-r5rw)

medium Tenable Cloud Security Plugin ID 444256

Description

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

 - Hey API is an ecosystem for turning API specifications into production-ready code. Prior to 0.97.3,
 dist/clients/core/params.ts ships a runtime template copied into generated SDKs as params.gen.ts, and
 buildClientParams writes unknown slot-prefixed keys such as $body_, $headers_, $path_, and $query_
 directly to the corresponding slot, allowing $query___proto__ alongside a legitimate q field to set
 params.query through params["query"]["__proto__"] = value, call Object.setPrototypeOf(params.query,
 value), and expose inherited attacker-controlled keys during for..in iteration. This issue is fixed in
 version 0.97.3. (CVE-2026-48819)

Solution

Update the @hey-api/openapi-ts library and its related packages to version 0.97.3 or later.
