Prior to 5.1.0, an unauthenticated attacker could initiate the OIDC login flow with an attacker-controlled redirectUrl. The login handling in auth\/oidc.go stored that URL with the opaque login state, and \/auth\/oidc\/logged\/{provider} appended the provider, token, and error values before redirecting the victim&#8217;s browser without validating the destination. Because the one-use token was not bound to the browser session that initiated login, an attacker who induced a victim to complete OIDC authentication could capture the token at the attacker-controlled destination and exchange it through \/auth\/oidc\/callback\/{provider} for the victim&#8217;s Kyoo session.
