CVE-2026-50282: Craft CMS CMS

Medium severity, CVSS 4.9. EPSS: 0.4% chance of exploitation in the next 30 days.

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.

Affected products

• Craft CMS CMS: from 5.0.0-RC1, before 5.9.21 (fixed in 5.9.21); from 4.0.0-RC1, up to and including 4.17.14
