CVE-2024-42471

02.09.2024, 18:15

actions/artifact is the GitHub ToolKit for developing GitHub Actions.  Versions of `actions/artifact` on the 2.x branch before 2.1.2 are vulnerable to arbitrary file write when using `downloadArtifactInternal`, `downloadArtifactPublic`, or `streamExtractExternal` for extracting a specifically crafted artifact that contains path traversal filenames. Users are advised to upgrade to version 2.1.2 or higher. There are no known workarounds for this issue.

Common Weakness Enumeration

CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
The software uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the software does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.
