  "details": "### Description\nApplications 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.\n\n### Resolution\nUpgrade auth0/symfony to version 5.9.0 or greater.\n\n### Acknowledgement\nOkta would like to thank Alex Yeara for their discovery.",
