CVE-2026-50157
Description
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.
