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.

Fencer Vulns keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.

CPEs and fixed versions use Anchore's correction of NVD's data: Added CPE configurations because not yet analyzed by NVD.
