# CVE-2022-36109: Moby vulnerability relating to supplementary group permissions > Attackers with container access can bypass group restrictions to escalate privileges, read sensitive data, or execute code within the container. - **Severity:** Medium 5.3 (`CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L`) - **Exploited in the wild:** Not known - **Login needed:** Any signed-in user - **Attackable:** Local or same network only - **Victim action needed:** Not needed - **Fix available:** Yes - **Published:** 9 Sep 2022 - **Updated:** 23 Apr 2025 - **Also known as:** CLEANSTART-2026-MS11283, DEBIAN-CVE-2022-36109, GHSA-rc4r-wh2q-q6c4, GO-2022-0985, OESA-2022-1936, SUSE-SU-2023:0795-1, SUSE-SU-2023:0795-2, SUSE-SU-2023:1625-1, UBUNTU-CVE-2022-36109, openSUSE-SU-2024:12790-1 ## What is CVE-2022-36109? CVE-2022-36109 is a medium-severity vulnerability in Fedoraproject Fedora, published on 9 Sep 2022. It can only be exploited from the same machine or local network, with no action from the victim. ### Official description Moby is an open-source project created by Docker to enable software containerization. A bug was found in Moby (Docker Engine) where supplementary groups are not set up properly. If an attacker has direct access to a container and manipulates their supplementary group access, they may be able to use supplementary group access to bypass primary group restrictions in some cases, potentially gaining access to sensitive information or gaining the ability to execute code in that container. This bug is fixed in Moby (Docker Engine) 20.10.18. Running containers should be stopped and restarted for the permissions to be fixed. For users unable to upgrade, this problem can be worked around by not using the `"USER $USERNAME"` Dockerfile instruction. Instead by calling `ENTRYPOINT ["su", "-", "user"]` the supplementary groups will be set up properly.

What it is: CVE-2022-36109 is a medium-severity vulnerability in Fedoraproject Fedora, published on 9 Sep 2022. It can only be exploited from the same machine or local network, with no action from the victim. Exploitation: There is no known exploitation of CVE-2022-36109 in the wild and no public exploit code. Affected packages and fixed versions: - github.com/docker/docker (Go): affected all versions; fixed in 20.10.18 - github.com/docker/docker (Go): affected all versions; fixed in 20.10.18 - github.com/docker/docker (Go): affected all versions; fixed in 20.10.18+incompatible Task: 1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies. 2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it. 3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead. 4. Run the tests and summarise what changed and why. 5. If nothing in the project is affected, say so and change nothing.
