## Summary

LatePoint, a WordPress appointment booking plugin, is affected by this vulnerability. An administrator (or a higher-privilege user) can inject malicious scripts into booking form settings that then run in the browsers of anyone who visits the booking form, including unauthenticated visitors on multisite installations.

Model-written summary (anthropic/claude-haiku-5.5). Verify details against the original sources.

## Affected

- Unknown Appointment Booking Plugin: fixed in 5.7.6

## Description

The Appointment Booking Plugin WordPress plugin before 5.7.6 does not escape several booking-form step content settings before rendering them on the public booking form, allowing high-privilege users such as administrators to inject JavaScript that executes in the browser of any visitor who loads the form; on multisite, where administrators do not hold the unfiltered_html capability, this crosses a privilege boundary to unauthenticated visitors.
