VikBooking < 1.6.8 - Broken Access Control

Description The plugin’s access control mechanism fails to properly restrict access to its settings, permitting any users that can access a menu to manipulate requests and perform unauthorized actions such as editing, renaming or deleting (categories for example) despite initial settings prohibiting such access. This vulnerability resembles broken access control, enabling unauthorized users to modify critical plugin configurations.
