GHSA-vxf5-wxwp-m7g9
MEDIUMGHSA-vxf5-wxwp-m7g9 is a medium-severity (CVSS 6.9) Open Redirect vulnerability in next. O3 Security confirms whether GHSA-vxf5-wxwp-m7g9 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Open Redirect in Next.js
Real-World Exposure
How broadly this vulnerability is actually deployed: weekly install volume shows current usage, and reverse-dependency count shows how many other packages break if it stays unpatched.
nextnpmDescription
Next.js is an open source website development framework to be used with the React library. In affected versions specially encoded paths could be used when pages/_error.js was statically generated, allowing an open redirect to occur to an external site. In general, this redirect does not directly harm users although it can allow for phishing attacks by redirecting to an attacker's domain from a trusted domain.
Impact
- Affected: Users of Next.js between
10.0.5and10.2.0 - Affected: Users of Next.js between
11.0.0and11.0.1usingpages/_error.jswithoutgetInitialProps - Affected: Users of Next.js between
11.0.0and11.0.1usingpages/_error.jsandnext export - Not affected: Deployments on Vercel (vercel.com) are not affected
- Not affected: Deployments with
pages/404.js - Note that versions prior to 0.9.9 package
nextnpm package hosted a different utility (0.4.1 being the latest version of that codebase), and this advisory does not apply to those versions.
We recommend upgrading to the latest version of Next.js to improve the overall security of your application.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for next. 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.
Fix
Update next to 11.1.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-vxf5-wxwp-m7g9 is resolved across your whole dependency graph.
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.
How O3 protects you
O3 pinpoints whether GHSA-vxf5-wxwp-m7g9 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-vxf5-wxwp-m7g9. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-vxf5-wxwp-m7g9 in your dependencies?
O3 detects GHSA-vxf5-wxwp-m7g9 across npm dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
