Which packages are affected by GHSA-gqf6-75v8-vr26?

GHSA-gqf6-75v8-vr26 affects the following packages: bin-links (npm). Ecosystems affected: npm.

How do I fix GHSA-gqf6-75v8-vr26?

Update bin-links to 1.1.5 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-gqf6-75v8-vr26 is resolved across your whole dependency graph.

How do I detect GHSA-gqf6-75v8-vr26 in my npm dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for bin-links. 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.

How do I mitigate GHSA-gqf6-75v8-vr26 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-gqf6-75v8-vr26?

O3 pinpoints whether GHSA-gqf6-75v8-vr26 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Is GHSA-gqf6-75v8-vr26 actively exploited in the wild?

No public exploit code has been indexed for GHSA-gqf6-75v8-vr26 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.

Description

Versions of bin-links prior to 1.1.5 are vulnerable to an Arbitrary File Write. The package fails to restrict access to folders outside of the intended node_modules folder through the bin field. This allows attackers to create arbitrary files in the system. Note it is not possible to overwrite files that already exist.

Recommendation

Upgrade to version 1.1.5 or later.
