Real-World Exposure
github.com/whyrusleeping/tar-utilsReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Go packages — download data is not available via public APIs for these ecosystems.
Description
Due to improper path sanitization, archives containing relative file paths can cause files to be written (or overwritten) outside of the target directory.

Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/whyrusleeping/tar-utils, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update github.com/whyrusleeping/tar-utils to 0.0.0-20201201191210-20a61371de5b or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-jpf8-h7h7-3ppm is resolved across your whole dependency graph.
Workarounds
Resolve every user-supplied path to its canonical form and reject anything that escapes the intended directory, and run the component under an account that has no read or write access outside the directory it legitimately serves.
