Summary

Auth0 Symfony SDK Accepted Bearer Tokens via URL Query Parameter

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.

Resolution

Upgrade auth0/symfony to version 5.9.0 or greater.

Acknowledgement

Okta would like to thank Alex Yeara for their discovery.

Severity

6.5 (Medium)

Title

Auth0 Symfony: Bearer Token Accepted via URL Query Parameter in Auth0 Symfony SDK

Summary

Auth0 Symfony is a Symfony SDK for Auth0 Authentication and Management APIs. From 5.0.0-BETA0 until 5.9.0, the Authorizer::authenticate() and Authorizer::supports() paths in the Authorizer security authenticator may accept OAuth 2.0 bearer access tokens from the token URL query parameter as well as the Authorization header for protected HTTP routes. Query-string tokens can be recorded in server logs, browser history, or referrer data and then replayed against protected API endpoints. This issue is fixed in version 5.9.0.

Severity
