Official description

Vvveb is a powerful and easy to use CMS with page builder to build websites, blogs or ecommerce stores. Prior to 1.0.8.3, the backend admin/auth-token endpoint allows an authenticated administrator to load another administrator's REST API token list by supplying that user's admin_id. This can disclose sensitive API tokens belonging to other administrators. This vulnerability is fixed in 1.0.8.3.
