CRITICALPterodactyl Panel Allows Unauthenticated Arbitrary Remote Code Execution
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
Pterodactyl is a free, open-source game server management panel. Prior to version 1.11.11, using the /locales/locale.json with the locale and namespace query parameters, a malicious actor is able to execute arbitrary code without being authenticated. With the ability to execute arbitrary code it could be used to gain access to the Panel's server, read credentials from the Panel's config, extract sensitive information from the database, access files of servers managed by the panel, etc. This issue has been patched in version 1.11.11. There are no software workarounds for this vulnerability, but use of an external Web Application Firewall (WAF) could help mitigate this attack.

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 1.11.11 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2025-49132 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 CVE-2025-49132 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 CVE-2025-49132. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is CVE-2025-49132 in your dependencies?
O3 detects CVE-2025-49132 across Packagist dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
