Summary
Craft CMS versions before 5.10.11 contain an authorization bypass vulnerability in ElementsController::actionDuplicate() that allows authenticated users with createEntries permission to delete peer provisional drafts. Attackers can exploit the deleteProvisionalDraft parameter to delete another user's unsaved draft without proper authorization checks, gaining access to the victim's in-progress content.
