CVE-2026-32265

Description

The Amazon S3 for Craft CMS plugin provides an Amazon S3 integration for Craft CMS. In versions 2.0.2 through 2.2.4, unauthenticated users can view a list of buckets the plugin has access to. The BucketsController->actionLoadBucketData() endpoint allows unauthenticated users with a valid CSRF token to view a list of buckets that the plugin is allowed to see. Users should update to version 2.2.5 of the plugin to mitigate the issue.
