What the vulnerability does
01Description
auth0-PHP is an SDK for Auth0 Authentication and Management APIs. In versions 3.3.0 through 8.16.0, the Bulk User Import endpoint in applications built with the SDK does not validate the file-path wrapper or value. Without proper validation, affected applications may accept arbitrary file paths or URLs. The vulnerability affects any application that either directly uses the Auth0-PHP SDK (versions 3.3.0–8.16.0) or indirectly relies on those versions through the Auth0/symfony, Auth0/laravel-auth0, or Auth0/wordpress SDKs. This issue is fixed in version 8.17.0.
