| Package Name | Ecosystem | Vulnerable Versions | First Patched Version |
|---|---|---|---|
| TShock | nuget | >= 4.3.21, < 5.2.1 | 5.2.1 |
The vulnerability stems from two key points: 1) OTAPI's RemoteClient.Reset() method fails to reset ClientUUID, leaving stale authentication data (CWE-613). 2) TShock's pre-patch Initialize() method didn't implement a workaround for this OTAPI limitation. The TShock fix explicitly adds an event handler to RemoteClient.Reset to nullify ClientUUID, confirming these were the vulnerable points. The first is the root cause in OTAPI, while the second represents TShock's failure to mitigate it initially.
