What is CVE-2026-50282?
CVE-2026-50282 is a medium-severity missing authorization vulnerability in craftcms cms, published on 2 Jul 2026. Any signed-in user can exploit it over the network, with no action from the victim.
Official description
Craft CMS is a content management system (CMS). Versions 5.0.0-RC1 and above, prior to 5.9.21 and versions 4.0.0-RC1 and above prior to 4.17.14 contain an authorization issue where a forced folder move can delete a conflicting destination folder without destination delete permission. Function craft\\controllers\\AssetsController::actionMoveFolder() supports moving an asset folder into a destination parent folder. If a folder with the same name already exists at the destination, the action can be called with force=true to overwrite the destination. This issue has been resolved in versions 5.9.21 and 4.17.14.
