CVE-2026-50282: CWE-862: Missing Authorization in craftcms cms
Craft 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 vulnerability. This flaw allows a forced folder move operation to delete a conflicting destination folder even if the user lacks delete permission on that destination. The issue occurs in the actionMoveFolder() method of the AssetsController when the force parameter is set to true to overwrite an existing folder. The vulnerability has been fixed in versions 5.9.21 and 4.17.14.
AI Analysis
Technical Summary
The vulnerability in Craft CMS involves a missing authorization check in the AssetsController::actionMoveFolder() method. When moving an asset folder into a destination parent folder, if a folder with the same name exists, the action can be forced to overwrite the destination folder by setting force=true. Due to insufficient authorization validation, this forced move can delete the destination folder even if the user does not have permission to delete it. This issue affects Craft CMS versions 5.0.0-RC1 and above prior to 5.9.21, and 4.0.0-RC1 and above prior to 4.17.14. The vulnerability is resolved in versions 5.9.21 and 4.17.14.
Potential Impact
An attacker with limited privileges (low privileges required) can delete asset folders in the destination location without having explicit delete permissions, potentially leading to unauthorized data loss or disruption of content management operations. The CVSS score of 4.9 indicates a medium severity impact with network attack vector and no user interaction required.
Mitigation Recommendations
This vulnerability has been fixed in Craft CMS versions 5.9.21 and 4.17.14. Users should upgrade to these versions or later to remediate the issue. No vendor advisory or patch links were provided, so verify the availability of these versions from official Craft CMS sources before upgrading. Patch status is not yet confirmed via vendor advisory; check official Craft CMS communications for current remediation guidance.
