Summary

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.

Fencer Vulns keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.

CPEs and fixed versions use Anchore's correction of NVD's data: Added CPE configurations because not yet analyzed by NVD.
