From 1.38.1 until 1.43.2 and 1.44.0, TempDirForURL in define/types.go does not securely confine Git repository subdirectories to the downloaded build context, and downloadToDirectory and stdinToDirectory can follow a Dockerfile symlink left by a partially extracted tar archive. A malicious server supplying a Git repository or tar archive can cause files outside the build context directory to be included in the context or copied into the build. This issue is fixed in versions 1.43.2 and 1.44.0.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:C/C:H/I:N/A:N","score":6.3},"cwes":["CWE-22"],"references":["https://github.com/podman-container-tools/buildah/commit/54459cf8a0feb4b1da766e4a6360451834e1846c","https://github.com/podman-container-tools/buildah/commit/fc2003bb2efeb3ed7d5c7e1e88d04e78f370a944","https://github.com/podman-container-tools/buildah/releases/tag/v1.43.2","https://github.com/podman-container-tools/buildah/releases/tag/v1.44.0","https://github.com/podman-container-tools/buildah/security/advisories/GHSA-49p4-px3h-rq49"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:49:38.260478770+00:00"},"epss":{"cve":"CVE-2026-44517","score":0.00184,"percentile":0.07889,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-49p4-px3h-rq49","url":"https://osv.dev/vulnerability/GHSA-49p4-px3h-rq49","summary":"Build breakout using malicious Containerfile and Git Smart HTTP server or GitHub release tar archive","modified":"2026-07-27T17:11:40.032962202Z","packages":[{"ecosystem":"Go","name":"github.com/containers/buildah","purl":"pkg:golang/github.com/containers/buildah","ranges":[">=1.38.1 <1.43.2"],"fixed":["1.43.2"]}]},{"id":"GO-2026-5116","url":"https://osv.dev/vulnerability/GO-2026-5116","summary":"Build breakout using malicious Containerfile or Git HTTP server in github.com/containers/buildah","modified":"2026-07-27T17:00:20.108518126Z","packages":[{"ecosystem":"Go","name":"github.com/containers/buildah","purl":"pkg:golang/github.com/containers/buildah","ranges":[">=1.38.1"],"fixed":[]}]}],"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).
