### 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. ### Acknowledgement Okta would like to thank Alex Yeara for their discovery.
