Description
Impact
This vulnerability impacts anyone running the affected versions of Wings. The vulnerability can potentially be used to access files and directories on the host system. The full scope of impact is exactly unknown, but reading files outside of a server's base directory (sandbox root) is possible.
In order to use this exploit, an attacker must have an existing "server" allocated and controlled by Wings. Details on the exploitation of this vulnerability are embargoed until March 27th, 2024 at 18:00 UTC.
Resolution
In order to mitigate this vulnerability, a full rewrite of the entire server filesystem was necessary. Because of this, the size of the patch is massive, however effort was made to reduce the amount of breaking changes. While tests were written to ensure security and functionality, there may be some semantic differences of certain operations, such as different errors being returned for example. If you notice any major semantic differences, please open an issue on our issue tracker so it can be resolved. https://github.com/pterodactyl/panel/issues/new/choose

Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/pterodactyl/wings, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update github.com/pterodactyl/wings to 1.11.9 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-494h-9924-xww9 is resolved across your whole dependency graph.
Workarounds
Resolve every user-supplied path to its canonical form and reject anything that escapes the intended directory, and run the component under an account that has no read or write access outside the directory it legitimately serves.
