Description
Summary
When a user signs into an account with 2FA enabled they are prompted to enter a token. When that token is used, it is not sufficiently marked as used in the system allowing an attacker that intercepts that token to then use it in addition to a known username/password during the token validity window.
This vulnerability requires that an attacker already be in possession of a valid username and password combination, and intercept a valid 2FA token (for example, during a screen share). The token must then be provided in addition to the username and password during the limited token validity window. The validity window is ~60 seconds as the Panel allows at most one additional window to the current one, each window being 30 seconds.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for pterodactyl/panel. 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 pterodactyl/panel to 1.12.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-rgmp-4873-r683 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-rgmp-4873-r683 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-rgmp-4873-r683. 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-rgmp-4873-r683 in your dependencies?
O3 detects GHSA-rgmp-4873-r683 across Packagist dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
