Summary
In tgstation-server 4.4.0 and 4.4.1, an authenticated user with permission to download logs can download any file on the server machine (accessible by the owner of the server process) via directory traversal ../ sequences in /Administration/Logs/ requests. The attacker is unable to enumerate files, however.
Exploit prediction
2.06% chance of exploitation in the next 30 days, higher than 81% of all scored CVEs (FIRST EPSS, 2026-11-08).
