GHSA-5822-pw57-vv37
GHSA-5822-pw57-vv37 is a security vulnerability in pterodactyl/panel. O3 Security confirms whether GHSA-5822-pw57-vv37 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
XSS vulnerability when listing users on add & modify server pages.
Real-World Exposure
pterodactyl/panel🐘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
An XSS vulnerability exists in versions of Pterodactyl Panel before 0.7.19. Affected versions do not properly sanitize account names before rendering them to the dropdown selector in the admin area when creating or modifying a server.
Patches
This XSS has been addressed in 0.7.19 and will be rolled forwards into the 1.0-rc.7 release.
Workarounds
No workaround exists without manual patching. See https://github.com/pterodactyl/panel/pull/2441/files for the files changed.

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 0.7.19 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-5822-pw57-vv37 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-5822-pw57-vv37 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-5822-pw57-vv37. 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-5822-pw57-vv37 in your dependencies?
O3 detects GHSA-5822-pw57-vv37 across Packagist dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
