Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

TShock versions before 5.2.2 allow clients that have not completed the connection handshake to occupy a player slot, chat, and receive server data. An attacker who connects without completing the handshake, including a player who is banned, can harass the server, observe traffic, and use server resources without being blocked. Upgrade to TShock 5.2.2 or later. The source says the issue does not affect servers behind a proxy that strictly enforces the handshake.
