GHSA-6rg3-8h8x-5xfv
MEDIUMGHSA-6rg3-8h8x-5xfv is a medium-severity (CVSS 6.4) vulnerability in github.com/pterodactyl/wings. O3 Security confirms whether GHSA-6rg3-8h8x-5xfv is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Unchecked hostname resolution could allow access to local network resources by users outside the local network
Real-World Exposure
github.com/pterodactyl/wingsReal-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
A newly implemented route allowing users to download files from remote endpoints was not properly verifying the destination hostname for user provided URLs. This would allow malicious users to potentially access resources on local networks that would otherwise be inaccessible.
This vulnerability requires valid authentication credentials and is therefore not exploitable by unauthenticated users. If you are running an instance for yourself or other trusted individuals this impact is unlikely to be of major concern to you. However, you should still upgrade for security sake.
Patches
Users should upgrade to the latest version of Wings.
Workarounds
There is no workaround available that does not involve modifying Panel or Wings code.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/pterodactyl/wings. 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 github.com/pterodactyl/wings to 1.2.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-6rg3-8h8x-5xfv 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-6rg3-8h8x-5xfv 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-6rg3-8h8x-5xfv. 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-6rg3-8h8x-5xfv in your dependencies?
O3 detects GHSA-6rg3-8h8x-5xfv across Go dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
