Machine-written summary

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

The Pterodactyl Panel package pterodactyl/panel is affected in versions before 1.12.3, and the fix is in 1.12.3. The account email change endpoint does not show the same protections as the login and password reset forms, such as reCAPTCHA or rate limiting, so an authenticated user with any valid account can send repeated requests with different addresses and learn whether each address is registered. This user enumeration could expose registered emails for use in phishing or other attacks. Upgrade to pterodactyl/panel 1.12.3 or later.
