Summary
Vulnerability in APITable up to 1.13.0-beta.1 allows an unauthenticated attacker to create notifications in the system. Missing required login for the create handler of InternalNotifyController and nginx proxy allow access to the API.
Risk Assessment
An attacker can impersonate the system and send fake notifications to any users, which could be used for phishing or manipulation.
Recommendation
Update APITable to a patched version or configure the nginx gateway to block unauthorized access to this endpoint.
Original NVD description (English source)
APITable through 1.13.0-beta.1 annotates the create handler of InternalNotifyController with requiredLogin = false. ResourceInterceptor honours that annotation by returning before any session or API key is validated, and the nginx gateway shipped with the product proxies every /api request to the backend server, so POST /api/v1/internal/notification/create is reachable by any unauthenticated client that can reach the gateway. An attacker can persist arbitrary notifications in apitable_player_notification against any user ID they name, and because fromUserId can be set to 0 the message is stored with the system sender and renders in the victim's inbox as a legitimate system notification. The body extras content is stored verbatim and forwarded to the frontend.
