Browser script execution via unneutralized comment parameter

Published Apr 22, 2025 · Updated Apr 23, 2025

Cross-site scripting in Hoteldruid 3.0.5 allows remote attackers to execute scripts in a user's browser through a crafted request. Hoteldruid processes the commento1_1 POST parameter without neutralizing script or HTML content before browser rendering. Exploitation requires a user to render the response; it can expose or alter browser-accessible data but does not interrupt the service.
