OliveTin gives access to predefined shell commands from a web interface. From 3000.0.0 until 3000.17.0, the service/internal/auth/otoauth2/restapi_auth_oauth2.go OAuth2 login handler stores per-login state in the registeredStates map on every /oauth/login request without expiring, deleting, or bounding entries, allowing an unauthenticated attacker to exhaust memory and cause a denial of service. This issue is fixed in version 3000.17.0.
