Description
Impact
This vulnerability impacts anyone running the affected versions of Wings. The vulnerability can be used to delete files and directories recursively on the host system. This vulnerability can be combined with GHSA-p8r3-83r8-jwj5 to overwrite files on the host system.
In order to use this exploit, an attacker must have an existing "server" allocated and controlled by Wings. Information on how the exploitation of this vulnerability works will be released on February 24th, 2023 in North America.
Patches
This vulnerability has been resolved in version v1.11.4 of Wings, and has been back-ported to the 1.7 release series in v1.7.4.
Anyone running v1.11.x should upgrade to v1.11.4 and anyone running v1.7.x should upgrade to v1.7.4.
Workarounds
None at this time.

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 1.7.4 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-66p8-j459-rq63 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-66p8-j459-rq63 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-66p8-j459-rq63. 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-66p8-j459-rq63 in your dependencies?
O3 detects GHSA-66p8-j459-rq63 across Go dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
