Description

Impact

A vulnerability exists in Pterodactyl Panel <= 1.6.6 that could allow a malicious attacker that compromises an API key to generate an authenticated user session that is not revoked when the API key is deleted, thus allowing the malicious user to remain logged in as the user the key belonged to.

It is important to note that a malicious user must first compromise an existing API key for a user to exploit this issue. It cannot be exploited by chance, and requires a coordinated attack against an individual account using a known API key.

Patches

This issue has been addressed in the v1.7.0 release of Pterodactyl Panel.
