CVE-2026-116899 Details
Description
REDAXO before 5.21.4 contains a broken access control vulnerability that allows authenticated editors to modify slices in unauthorized categories by pairing a permitted article with a foreign slice id. Attackers can abuse content/edit delete and edit functions or the content_slice_status and content_move_slice APIs to delete, toggle, move, or overwrite other editors' slices.
A broken access control vulnerability has been identified in REDAXO versions prior to 5.21.4. This vulnerability allows authenticated editors to modify slices in categories for which they do not have permission. The issue arises because the permission check is based on the article provided in the request, while the actual modification is made to a slice from a different category. Exploitation can be achieved by using the content/edit delete and edit functions, or the content_slice_status and content_move_slice APIs, to manipulate other editors' slices.
Users can upgrade to REDAXO version 5.21.4 or later to address this vulnerability.
