Description

The vulnerability allows a remote user to retain access to an active WebSocket session after token revocation or device removal.

The vulnerability exists due to improper access control in src/gateway/server-methods/devices.ts and src/gateway/server.impl.ts when handling device removal or token revocation for existing WebSocket connections. A remote user can continue using an already-authenticated live session to retain access to an active WebSocket session after token revocation or device removal.

The session remains usable until it reconnects.
