Wings is the server control plane for the Pterodactyl game-server management panel. In versions up to and including 1.13.2, the SFTP write path does not enforce a server's disk quota during a transfer, allowing a tenant with SFTP write access to a single server to exhaust the host node's physical disk and take down every server on it. Wings checks available space only once, as a boolean, when the write handle is opened, using a stale cached usage value and without knowing the size of the incoming data, and it then returns a raw, unaccounted file handle that is never re-checked as the transfer proceeds. A single upload can therefore be written without bound, far beyond the configured disk limit, until the node's disk is full, and because a server stopped for exceeding its limit is not treated as suspended, SFTP writes are still accepted even after the quota is already exceeded. This issue is fixed in version 1.13.3.
