Published Mar 7, 2025 · Updated Jan 9, 2026

Stored cross-site scripting in Reservit Hotel before 3.0 allows remote authenticated users to run script in an administrator's browser. The Content page saves the Button text > French setting without sanitizing or escaping it and renders the stored value when the dashboard is reopened. Administrator privileges are required, and exploitation still works when unfiltered_html is disabled, including in multisite installations.
