Rill 0.77.0 through 0.90.5 contains a missing authorization vulnerability in the admin OAuth server that issues authorization codes to dynamically registered clients without user consent. Attackers can register a client with the long_lived_access_token scope and lure a user to an authorization link, obtaining a non-expiring API token with the user's full permissions.
