GHSA-384w-wffr-x63q
MEDIUMPterodactyl panel's admin area vulnerable to Cross-site Scripting
EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.
Blast Radius
pterodactyl/panelReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Packagist packages — download data is not available via public APIs for these ecosystems.
Description
Impact
Importing a malicious egg or gaining access to wings instance could lead to XSS on the panel, which could be used to gain an administrator account on the panel. Specifically, the following things are impacted:
- Egg Docker images
- Egg variables:
- Name
- Environment variable
- Default value
- Description
- Validation rules
Additionally, certain fields would reflect malicious input, but it would require the user knowingly entering such input to have an impact.
To iterate, this would require an administrator to perform actions and can't be triggered by a normal panel user.
Workarounds
No workaround is available other than updating to the latest version of the panel.

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 1.11.6 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-384w-wffr-x63q 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-384w-wffr-x63q 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-384w-wffr-x63q. 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-384w-wffr-x63q in your dependencies?
O3 detects GHSA-384w-wffr-x63q across Packagist dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
