What fixes it

A fixed version on one release line is not the upgrade target for every line. Check your exact version and any vendor backports.

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.
