It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-41089 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/docker/docker (Go): affected all versions; fixed in 20.10.9\n- github.com/docker/docker (Go): affected all versions; fixed in 20.10.9\n- github.com/docker/docker (Go): affected all versions; fixed in 20.10.9+incompatible\n- github.com/moby/moby (Go): affected all versions; fixed in 20.10.9+incompatible\n\nTask:\n1. 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.\n2. 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.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2021-41089/ (Markdown: https://insights.sbomify.com/CVE-2021-41089/index.md)","id":"CVE-2021-41089","markdown":"https://insights.sbomify.com/CVE-2021-41089/index.md","name":"CVE-2021-41089","record":{"aliases":["CLEANSTART-2026-HF26870","DEBIAN-CVE-2021-41089","GHSA-v994-f8vw-g7j4","GO-2024-2913","UBUNTU-CVE-2021-41089","USN-5103-1","openSUSE-SU-2024:11579-1"],"analysis":{"component_type":"container_or_infrastructure","fix_type":"upgrade","impacts":["privilege_escalation","security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Docker Engine","requires_auth":"low_privilege","summary":"Attackers can use docker cp to modify host file permissions, potentially widening access to sensitive files on the host system.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"fedora","vendor":"fedoraproject"},{"product":"moby","vendor":"mobyproject"}],"cvss":{"score":2.8,"severity":"low","source":"cna","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:C/C:L/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-281","name":"Improper Preservation of Permissions"}],"description":"Moby is an open-source project created by Docker to enable software containerization. A bug was found in Moby (Docker Engine) where attempting to copy files using `docker cp` into a specially-crafted container can result in Unix file permission changes for existing files in the host’s filesystem, widening access to others. This bug does not directly allow files to be read, modified, or executed without an additional cooperating process. This bug has been fixed in Moby (Docker Engine) 20.10.9. Users should update to this version as soon as possible.
