Machine-written summary

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

Tgstation-server versions from 4.0.0 before 6.8.0 (Tgstation.Server.Api and Tgstation.Server.Host NuGet packages) let low-privileged users with the "Set .dme Path" permission compile and run .dme files that sit on the host outside the deployment directory. An attacker who holds that permission, plus the separate privilege needed to place such files, could escalate to remote code execution through BYOND's shell() proc on servers running in the trusted security level. Upgrade to version 6.8.0 or later. Until then, do not grant the Deployment permission to set a .dme path to untrusted users.
