Technical details
An authorization bypass exists in the `EntriesController::actionMoveToSection()` endpoint of Craft CMS. The root cause is an insufficient permission check: the controller verifies if a user has `viewEntries` permission for the destination section but fails to verify the required `saveEntries` permission. An attacker authenticated to the control panel can exploit this by sending a request to move an entry they already control into a destination section where they only have read access. This allows the attacker to relocate content into unauthorized sections, bypassing the intended section-level authorization model. The issue is fixed in version 5.9.21.
