Description
Wings is the server control plane for Pterodactyl, a free, open-source game server management panel. Prior to version 1.12.0, websockets within wings lack proper rate limiting and throttling. As a result a malicious user can open a large number of connections and then request data through these sockets, causing an excessive volume of data over the network and overloading the host system memory and cpu. Additionally, there is not a limit applied to the total size of messages being sent or received, allowing a malicious user to open thousands of websocket connections and then send massive volumes of information over the socket, overloading the host network, and causing increased CPU and memory load within Wings. Version 1.12.0 patches the issue.

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, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update github.com/pterodactyl/wings to 1.12.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2025-69199 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 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like CVE-2025-69199 can be triaged on real exposure rather than presence alone.
Tailored to CVE-2025-69199. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
