GHSA-c479-wq8g-57hr
MEDIUMPterodactyl Panel has plain-text logging of user passwords when two-factor authentication is disabled
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.

Description
Impact
When a user disables two-factor authentication via the Panel, a DELETE request with their current password in a query parameter will be sent. While query parameters are encrypted when using TLS, many webservers (including ones officially documented for use with Pterodactyl) will log query parameters in plain-text, storing a user's password in plain text.
If a malicious user obtains access to these logs they could potentially authenticate against a user's account; assuming they are able to discover the account's email address or username separately.
Patches
This problem has been patched by https://github.com/pterodactyl/panel/commit/8be2b892c3940bdc0157ccdab16685a72d105dd1 on the 1.0-develop branch and released under v1.11.8 as a single commit on top of v1.11.7 https://github.com/pterodactyl/panel/commit/75b59080e2812ced677dab516222b2a3bb34e3a4
Patch file: https://github.com/pterodactyl/panel/commit/8be2b892c3940bdc0157ccdab16685a72d105dd1.patch
Workarounds
There are no workarounds at this time. There is not a direct vulnerability within the software as it relates to logs generated by intermediate components such as webservers or Layer 7 proxies.
Updating to v1.11.8 or adding the linked patch manually are the only ways to avoid this problem.
User Notice
As this vulnerability relates to historical logging of sensitive data, users who have ever disabled 2FA on a Panel (self-hosted or operated by a company) should change their passwords and consider enabling 2FA if it was left disabled. While it's unlikely that your account will be compromised by this vulnerability, it's not impossible.
Panel administrators should consider clearing any access logs that may contain sensitive data, for Panels using NGINX, the access log is located at /var/log/nginx/pterodactyl.app-access.log.

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 1.11.8 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-c479-wq8g-57hr 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-c479-wq8g-57hr 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-c479-wq8g-57hr. 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-c479-wq8g-57hr in your dependencies?
O3 detects GHSA-c479-wq8g-57hr across Packagist dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
