In versions prior to 29.5.1 and in moby/moby v2 prior to v2.0.0-beta.14, when a compressed archive is uploaded to a container via `PUT /containers/{id}/archive` or piped through `docker cp -`, the daemon resolves decompression binaries (such as `xz` or `unpigz`) from the container's filesystem rather than the host's due to incorrect ordering of operations. A malicious container image containing a trojanized decompression binary can achieve arbitrary code execution with full daemon privileges, including host root UID and unrestricted capabilities, when a user uploads a compressed (xz or gzip) archive into that container. This issue is fixed in Docker Engine 29.5.1 and moby/moby v2.0.0-beta.14. Workarounds include only running containers from trusted images, using authorization plugins to restrict access to the `PUT /containers/{id}/archive` endpoint, and avoiding piping compressed archives into containers created from untrusted images","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:R/S:C/C:H/I:H/A:N","score":7.2},"cwes":["CWE-427"],"references":["https://github.com/moby/moby/security/advisories/GHSA-x86f-5xw2-fm2r","https://access.redhat.com/errata/RHSA-2026:37387","https://access.redhat.com/errata/RHSA-2026:41030","https://access.redhat.com/errata/RHSA-2026:42852","https://access.redhat.com/errata/RHSA-2026:44622"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:37:48.043517290+00:00"},"epss":{"cve":"CVE-2026-41567","score":0.00155,"percentile":0.04597,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-x86f-5xw2-fm2r","url":"https://osv.dev/vulnerability/GHSA-x86f-5xw2-fm2r","summary":"Docker: `PUT /containers/{id}/archive` executes container binary on the host","modified":"2026-09-10T03:50:47.998689316Z","packages":[{"ecosystem":"Go","name":"github.com/moby/moby/v2","purl":"pkg:golang/github.com/moby/moby/v2","ranges":["<2.0.0-beta.14"],"fixed":["2.0.0-beta.14"]},{"ecosystem":"Go","name":"github.com/docker/docker","purl":"pkg:golang/github.com/docker/docker","ranges":["<=28.5.2"],"fixed":[]},{"ecosystem":"Go","name":"github.com/moby/moby","purl":"pkg:golang/github.com/moby/moby","ranges":["<=28.5.2"],"fixed":[]}]},{"id":"GO-2026-5746","url":"https://osv.dev/vulnerability/GO-2026-5746","summary":"Docker: 'PUT /containers/{id}/archive' executes container binary on the host in github.com/docker/docker","modified":"2026-07-23T17:45:22.600659583Z","packages":[{"ecosystem":"Go","name":"github.com/docker/docker","purl":"pkg:golang/github.com/docker/docker","ranges":["all versions"],"fixed":[]},{"ecosystem":"Go","name":"github.com/moby/moby","purl":"pkg:golang/github.com/moby/moby","ranges":["all versions"],"fixed":[]},{"ecosystem":"Go","name":"github.com/moby/moby/v2","purl":"pkg:golang/github.com/moby/moby/v2","ranges":["<2.0.0-beta.14"],"fixed":["2.0.0-beta.14"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
