CVE-2026-32266Network attack vector

Unauthenticated bucket disclosure via missing administrator check

Published Mar 18, 2026 · Updated Mar 18, 2026

Information disclosure in Google Cloud Storage for Craft CMS before 2.2.1 allows remote attackers to list accessible storage buckets. DefaultController::actionLoadBucketData returns bucket data after request-format checks but, before the patch, performs no administrator authorization check. Exploitation requires a valid CSRF token and reveals bucket identities available to the configured service account, not bucket contents or modification access.
