What is CVE-2026-81566?

CVE-2026-81566 is a medium-severity missing authorization vulnerability in joomshaper.com SP Page Builder (Free and Pro) extension for Joomla, published on 14 Sep 2026. An attacker needs administrator access to exploit it, with no action from the victim.

Official 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.

Weakness: CWE-284
