The extractor decides where each archive entry lands using lexical string checks and then performs the filesystem operation on a path that is resolved by the OS, so links introduced by the archive can be followed out of the destination directory. An attacker who controls the contents of an archive can create or overwrite files at arbitrary paths writable by the extracting process.","cvss_v4":{"vector":"CVSS:4.0/AV:L/AC:L/AT:P/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","score":7.1},"cvss_v3":null,"cwes":["CWE-59"],"references":["https://docs.docker.com/desktop/release-notes/#4860","https://docs.docker.com/engine/release-notes/29/#2970","https://github.com/docker/cli/releases/tag/v29.7.0","https://github.com/docker/compose/releases/tag/v5.4.0","https://github.com/docker/sbx-releases/releases/tag/v0.38.0"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:49:10.689564601+00:00"},"epss":{"cve":"CVE-2026-17106","score":0.0044,"percentile":0.3829,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-hfg8-hc9c-6c3h","url":"https://osv.dev/vulnerability/GHSA-hfg8-hc9c-6c3h","summary":"moby/go-archive: Crafted tar archive can write outside the extraction directory","modified":"2026-09-10T03:50:53.613234195Z","packages":[{"ecosystem":"Go","name":"github.com/moby/go-archive","purl":"pkg:golang/github.com/moby/go-archive","ranges":["<0.3.0"],"fixed":["0.3.0"]}]},{"id":"GO-2026-6253","url":"https://osv.dev/vulnerability/GO-2026-6253","summary":"moby/go-archive: Crafted tar archive can write outside the extraction directory in github.com/moby/go-archive","modified":"2026-09-01T21:56:10.665183640Z","packages":[{"ecosystem":"Go","name":"github.com/moby/go-archive","purl":"pkg:golang/github.com/moby/go-archive","ranges":["<0.3.0"],"fixed":["0.3.0"]}]}],"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).
