## Affected

- joomshaper.com SP Page Builder (Free and Pro) extension for Joomla: 4.0.0 - 6.9.0

## Description

Joomla Extension - joomshaper.com - Missing Access Control in Menu Item Creation in SP Page Builder (Free and Pro) 4.0.0 - 6.9.0 - The add-to-menu routine invoked the com_menus item model's save() method directly. That model does not perform authorisation itself, because the relevant checks reside in the com_menus controller, and the only check applied was core.edit on com_sppagebuilder. Users with no permissions whatsoever on com_menus could therefore create menu items, and because the record identifier was taken from the submitted jform[menuid] field, could also overwrite existing ones. The home flag was read back from the database and preserved, so the site's home menu item could be repointed while remaining the home item.
