CVE-2024-34067 — Pterodactyl is a free, open-source game server management panel built with PHP, React, and Go

Medium CVSS 6.1

Pterodactyl is a free, open-source game server management panel built with PHP, React, and Go. Importing a malicious egg or gaining access to wings instance could lead to cross site scripting (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 and 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. This issue has has been addressed in version 1.11.6 and users are advised to upgrade. No workaround is available other than updating to the latest version of the panel.

Cross-site scripting and unsafe browser output

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Trace reflected, stored, and DOM-derived untrusted values into HTML, attributes, URLs, styles, scripts, and client-side template sinks.
  • Identify affected origins, authenticated user roles, sensitive browser capabilities, and where content is shared across tenants.
  • Review framework escaping, rich-text sanitization, legacy templates, and client-side rendering paths.

Remediate safely

  • Use context-aware framework output encoding and safe DOM APIs; keep untrusted data out of executable contexts.
  • Sanitize intentionally supported markup with a maintained allowlist policy and validate URLs and attributes separately.
  • Update affected rendering components and add tests for every output context using inert sentinel markup.
