Authenticated asset deletion via target-only permission check
Published Jul 1, 2026 · Updated Jul 1, 2026
Missing authorization in Craft CMS 4.0.0-RC1 through 4.17.13 and 5.0.0-RC1 through 5.9.20 allows remote authenticated users to delete assets. AssetsController::actionReplaceFile checks replace permission only against the target when both assetId and sourceAssetId are supplied, then deletes the source without checking its volume permissions. Access requires file-replacement permission in one volume and a source asset ID; exploitation can delete protected assets, break content references, and cause data loss.
