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 commenus item model's save() method directly. That model does not perform authorisation itself, because the relevant checks reside in the commenus controller, and the only check applied was core.edit on comsppagebuilder. Users with no permissions whatsoever on commenus 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.
