Advisory details

Description

Applications built with the Auth0 Symphony SDK, using the Authorizer security authenticator to protect HTTP routes may accept OAuth 2.0 bearer access tokens provided through a URL query parameter, in addition to the standard Authorization header, which may increase the risk of access token exposure and replay against protected API endpoints.
