CVE-2026-44012Network attack vector

Authenticated asset hierarchy disclosure via missing authorization

Published May 12, 2026 · Updated May 12, 2026

Missing authorization in Craft CMS 5.0.0-RC1 through 5.9.17 allows remote authenticated users to read asset names and folder metadata. The actionShowInFolder method accepts an arbitrary asset ID, queries Asset::findOne without an editable or savable scope, and serializes the filename and full volume folder hierarchy without enforcing viewAssets or viewPeerAssets. Any control-panel account with accessCp permission can enumerate metadata for volumes it cannot view, but the flaw does not disclose asset contents directly.
