DescriptionGitHub Advisory

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.

AnalysisAI

The BucketsController endpoint in this plugin suffers from an information disclosure vulnerability where unauthenticated attackers possessing a valid CSRF token can enumerate the list of accessible buckets. This exposure allows reconnaissance of cloud storage resources available to the plugin without requiring authentication. Update to version 2.2.5 to resolve this issue.

Technical ContextAI

Information disclosure occurs when an application inadvertently reveals sensitive data to unauthorized actors through error messages, logs, or improper access controls. This vulnerability is classified as Information Exposure (CWE-200).

RemediationAI

A vendor patch is available — apply it immediately. Implement proper access controls. Sanitize error messages in production. Review logging practices to avoid capturing sensitive data.
