How to fix?

Upgrade @strapi/strapi to version 4.10.8 or higher.

Overview

@strapi/strapi is an updated version of the old 'strapi', which is a free and open-source headless CMS delivering your content anywhere you need.

Affected versions of this package are vulnerable to Information Exposure by developers, users, or plugins, all of who can make every attribute of a Content-Type public without knowing it. The privateAttributes getter is removed when content types are modified, which can result in any attribute becoming public.

NOTE: If a user mutates the content-type they will not be affected.

PoC

strapi.container.get('content-types').extend(contentTypeUID, (contentType) => {
  const newCT = { ... contentType, attributes: { ...contentType.attributes, newAttr: {} } };
  return newCT;
});

Copying a content-type causes the getter to be removed.
