How severe is GHSA-94vh-gphv-8pm8?

No CVSS score has been assigned to GHSA-94vh-gphv-8pm8 yet. Review the advisory details and affected package list to assess your exposure.

Which packages are affected by GHSA-94vh-gphv-8pm8?

GHSA-94vh-gphv-8pm8 affects the following packages: zip (crates.io). Ecosystems affected: crates.io.

How do I fix GHSA-94vh-gphv-8pm8?

Update zip to 2.3.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-94vh-gphv-8pm8 is resolved across your whole dependency graph.

How do I detect GHSA-94vh-gphv-8pm8 in my crates.io dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for zip, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate GHSA-94vh-gphv-8pm8 if there is no patch (or I can't update yet)?

If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

How does O3 Security protect against GHSA-94vh-gphv-8pm8?

O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-94vh-gphv-8pm8 can be triaged on real exposure rather than presence alone.

Is GHSA-94vh-gphv-8pm8 actively exploited in the wild?

No public exploit code has been indexed for GHSA-94vh-gphv-8pm8 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

What is the EPSS score for GHSA-94vh-gphv-8pm8?

GHSA-94vh-gphv-8pm8 has an EPSS (Exploit Prediction Scoring System) score of 0.6%, placing it in the 45th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

What type of vulnerability is GHSA-94vh-gphv-8pm8?

GHSA-94vh-gphv-8pm8 is classified as Path Traversal (CWE-22), CWE-61 (CWE-61), CWE-180 (CWE-180). These weakness types describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation. This is a high-impact weakness class that often enables remote code execution or data exposure.

When was GHSA-94vh-gphv-8pm8 published, and has it been updated?

GHSA-94vh-gphv-8pm8 was published on March 17, 2025 and was last updated on September 10, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects crates.io packages — download data is not available via public APIs for these ecosystems.

Description

Summary

In the archive extraction routine of affected versions of the zip crate, symbolic links earlier in the archive are allowed to be used for later files in the archive without validation of the final canonicalized path, allowing maliciously crafted archives to overwrite arbitrary files in the file system when extracted.

Details

This is a variant of the zip-slip vulnerability, we can make the extraction logic step outside of the target directory by creating a symlink to the parent directory and then extracting further files through that symlink.

The documentation of the [::zip::read::ZipArchive::extract] method is in my opinion implying this should not happen:

"Paths are sanitized with ZipFile::enclosed_name." ... [::zip::read::FileOptions::enclosed_name] ... is resistant to path-based exploits ... can’t resolve to a path outside the current directory.

Most archive software either decline to extract symlinks that traverse out of the directory or defer creation of symlinks after all files have been created to prevent unexpected behavior when later entries depend on earlier symbolic link entries.

Impact

Users who extract untrusted archive files using the following high-level API method may be affected and critical files on the system may be overwritten with arbitrary file permissions, which can potentially lead to code execution.
