Real-World Exposure
github.com/anchore/stereoscopeReal-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
Impact
It is possible to craft an OCI tar archive that, when stereoscope attempts to unarchive the contents, will result in writing to paths outside of the unarchive temporary directory. Specifically, use of github.com/anchore/stereoscope/pkg/file.UntarToDirectory() function, the github.com/anchore/stereoscope/pkg/image/oci.TarballImageProvider struct, or the higher level github.com/anchore/stereoscope/pkg/image.Image.Read() function express this vulnerability.
Patches
Patched in v0.0.1
Workarounds
If you are using the OCI archive as input into stereoscope then you can switch to using an OCI layout by unarchiving the tar archive and provide the unarchived directory to stereoscope.

Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/anchore/stereoscope, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update github.com/anchore/stereoscope to 0.0.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-hpxr-w9w7-g4gv 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.
