| Name | CVE-2026-44517 |
| Description | Buildah is a tool that facilitates building OCI images. 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. |
