Auth0 Symfony SDK Accepted Bearer Tokens via URL Query Parameter

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.

Resolution

Upgrade auth0/symfony to version 5.9.0 or greater.
