• CVE-2024-41799: 1.21% estimated exploitation activity in the next 30 days; percentile 68.47 (FIRST EPSS, 2026-11-03). This is a model estimate, not proof of exploitation or customer exposure.

As published by the source; long descriptions are shortened.

Impact What kind of vulnerability is it? Who is impacted? Low permission users using the "Set .dme Path" privilege could potentially set malicious .dme files existing on the host machine to be compiled and executed. These .dme files could be uploaded via tgstation-server (requiring a separate, isolated privilege) or some other means. A 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. The 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.

# Patch Next advisory brief: CVE-2024-41799

Advisory: tgstation-server's DreamMaker environment files outside the deployment directory can be compiled and ran by insufficiently permissioned users
IDs: CVE-2024-41799, GHSA-c3h4-9gc2-f7h4
Record: https://patchnext.com/advisories/cve-2024-41799 (revision 1, source checked 26 Oct 2026, 17:00 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 7.3)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: tgstation.server.api 6.8.0; tgstation.server.host 6.8.0. A vendor fix does not mean a deployment is fixed.

## Affected components
- NuGet tgstation.server.api: affected >= 4.0.0, < 6.8.0; fixed in 6.8.0
- NuGet tgstation.server.host: affected >= 4.0.0, < 6.8.0; fixed in 6.8.0

## Suggested inspection (read-only)
- NuGet tgstation.server.api: check the installed version with your package manager.
- NuGet tgstation.server.host: check the installed version with your package manager.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on tgstation.server.api, tgstation.server.host.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.

## Sources
- Verified: https://github.com/advisories/GHSA-c3h4-9gc2-f7h4 (GitHub-reviewed advisory GHSA-c3h4-9gc2-f7h4 lists affected ranges: NuGet tgstation.server.api >=4.0.0 =4.0.0 <6.8.0)
