CVE-2026-32265: Craft CMS Aws-s3

Medium severity, CVSS 6.9. EPSS: 0.5% chance of exploitation in the next 30 days.

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.

Affected products

• Craft CMS Aws-s3: from 2.0.2, before 2.2.5 (fixed in 2.2.5)
