The artifact name and `--dir` flag are used to determine the artifact’s download path.  When the artifact is named `..`, the resulting files within the artifact are extracted exactly 1 directory higher than the specified `--dir` flag value.\n\nIn `2.63.1`, `gh run download` will not download artifacts named `..` and `.` and instead exit with the following error message:\n\n```\nerror downloading ..: would result in path traversal\n```\n\n### Impact\n\nSuccessful exploitation heightens the risk of local path traversal attack vectors exactly 1 directory higher than intended.\n\n### Remediation and Mitigation\n\n1. Upgrade `gh` to `2.63.1`\n2. Implement additional validation to ensure artifact filenames do not contain potentially dangerous patterns, such as `..`, to prevent path traversal risks.\n\n## Affected packages\n\n- `github.com/cli/cli/v2 < 2.63.1`\n- `github.com/cli/cli <= 1.14.0`\n\n## Remediation\n\nUpgrade to a patched release:\n\n- `github.com/cli/cli/v2 2.63.1`","depth":"sunlit","depthScore":28,"depthScoreParts":{"impact":27.5,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
