+  "summary": "tgstation-server's DreamMaker environment files outside the deployment directory can be compiled and ran by insufficiently permissioned users",
+  "details": "### Impact\n_What kind of vulnerability is it? Who is impacted?_\n\nLow permission users using the \"Set .dme Path\" privilege could potentially set malicious .dme files existing on the host machine to be compiled and executed. \n\nThese .dme files could be uploaded via tgstation-server (requiring a separate, isolated privilege) or some other means.\n\nA server configured to execute in BYOND's trusted security level (requiring a third separate, isolated privilege OR being set by another user) could lead to this escalating into remote code execution via BYOND's shell() proc.\n\nThe ability to execute this kind of attack is a known side effect of having privileged TGS users, but normally requires multiple privileges with known weaknesses. This vector is not intentional as it does not require control over the where deployment code is sourced from and _may_ not require remote write access to an instance's `Configuration` directory.\n\n### Patches\n_Has the problem been patched? What versions should users upgrade to?_\n\nThis problem is patched by pull request #1835 and fixed in versions 6.8.0 and above.\n\n### Workarounds\n_Is there a way for users to fix or remediate the vulnerability without upgrading?_\n\nDo not give un-trusted users the Deployment permission to set a .dme path on instances.\n",
