AI-suggested
Upgrade to Authlib version 1.6.11 or later, where the CSRF protection on the cache feature in authlib.integrations.starlette_client.OAuth has been implemented. No other mitigation is required as the issue is fixed in this release.
Description
Authlib versions prior to 1.6.11 lack Cross-Site Request Forgery (CSRF) protection on the cache feature within authlib.integrations.starlette_client.OAuth. This vulnerability allows an attacker to potentially perform unauthorized actions via forged requests. The issue is addressed in version 1.6.11.
