Reference: CVE-2025-49132

1. What is being reported?

The vulnerability allows someone to run harmful commands on the server hosting the Pterodactyl panel by exploiting a specific part of the software that handles language settings. This can happen without any login or authentication, meaning an attacker can gain full access remotely.

2. What this means in plain English

If your organisation uses Pterodactyl to manage game servers, an attacker could take over the server, steal passwords, access private data, or damage your systems. This could lead to data loss, service interruptions, or worse.

3. Could this affect a small business?

This mainly affects organisations that use Pterodactyl to manage game servers. If you do not use this software, you are unlikely to be affected. However, if you are unsure whether you use it, check with your IT provider.

4. What to do now

  • Check if your organisation uses Pterodactyl for game server management.
  • If you do, ensure it is updated to version 1.11.11 or later, where the issue is fixed.
  • If you cannot update immediately, consider using an external Web Application Firewall (WAF) to help block attacks.
  • Ask your IT provider to review your server security and monitor for unusual activity.

5. Ask your IT provider

Can you confirm if we use Pterodactyl for managing any game servers, and if so, has it been updated to version 1.11.11 or later to fix the critical security vulnerability CVE-2025-49132?

6. Bottom line

Update Pterodactyl promptly to protect your servers from remote takeover and data theft.
