Original source description
This module enables you to display content in tabs, where each tab renders a block, a node, a view, or another Quick Tabs instance.
The module did not correctly enforce access when rendering node and block tabs. It treated a neutral access result as a grant for node tabs and block plugins, and performed no access check for reusable custom blocks. Content that should have been denied was therefore rendered — for example, an unpublished node or unpublished reusable custom block could be shown to users without permission to view it.
The access bypass is mitigated by the fact that affected content is selected by a user with the “administer quicktabs” permission when the tab is configured, so an attacker cannot choose which content is exposed.
