GHSA-27pv-q55r-222g

HIGH

GHSA-27pv-q55r-222g is a high-severity (CVSS 7.7) Path Traversal vulnerability in github.com/ipfs/go-ipfs. O3 Security confirms whether GHSA-27pv-q55r-222g is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.

Description

Impact

It is currently possible for path traversal to occur with DAGs containing relative paths during retrieval. This can cause files to be overwritten, or written to incorrect output directories. The issue can only occur when ipfs get is done on an affected DAG.

  1. The only affected command is ipfs get.
  2. The gateway is not affected.

Patches

Traversal fix patched in https://github.com/whyrusleeping/tar-utils/commit/20a61371de5b51380bbdb0c7935b30b0625ac227 tar-utils patch applied to go-ipfs via https://github.com/ipfs/go-ipfs/commit/b7ddba7fe47dee5b1760b8ffe897908417e577b2

Workarounds

Upgrade to go-ipfs 0.8 or later.

Detection & mitigation playbook

Open-source dependency
  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/ipfs/go-ipfs. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.

  2. Fix

    Update github.com/ipfs/go-ipfs to 0.8.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-27pv-q55r-222g is resolved across your whole dependency graph.

  3. Workarounds

    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.

  4. How O3 protects you

    O3 pinpoints whether GHSA-27pv-q55r-222g is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Tailored to GHSA-27pv-q55r-222g. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.

Is GHSA-27pv-q55r-222g in your dependencies?

O3 detects GHSA-27pv-q55r-222g across Go dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
