Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Pterodactyl Panel versions 1.7.0 up to but not including 1.13.0 apply one shared rate-limit bucket to the login and two-factor checkpoint endpoints instead of keying it per client. An unauthenticated attacker on a single IP can exhaust that bucket with about 10 requests per minute, causing HTTP 429 responses to all users attempting to log in or complete 2FA for as long as the attack continues. Upgrade to Pterodactyl Panel 1.13.0 or later.
