CVE-2024-8432Network attack vector

Subscriber-level CSS modification via unchecked appearance save

Published Sep 24, 2024 · Updated Apr 8, 2026

Missing authorization in Webba Booking 5.0.48 and earlier allows remote authenticated users to alter the booking form's CSS. The save_appearance() function persists submitted appearance settings without checking whether the requester has the capability required to change them. Subscriber-level access is sufficient, and the bounded consequence is unauthorized modification of the form's presentation rather than broader site control.
