SCA: security update for @koa/cors (GHSA-qxrj-hx23-xp82)

high Tenable Self-Hosted Container Security Plugin ID 418415

Description

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

 - @koa/cors npm provides Cross-Origin Resource Sharing (CORS) for koa, a web framework for Node.js. Prior to
 version 5.0.0, the middleware operates in a way that if an allowed origin is not provided, it will return
 an `Access-Control-Allow-Origin` header with the value of the origin from the request. This behavior
 completely disables one of the most crucial elements of browsers - the Same Origin Policy (SOP), this
 could cause a very serious security threat to the users of this middleware. If such behavior is expected,
 for instance, when middleware is used exclusively for prototypes and not for production applications, it
 should be heavily emphasized in the documentation along with an indication of the risks associated with
 such behavior, as many users may not be aware of it. Version 5.0.0 fixes this vulnerability.
 (CVE-2023-49803)
