Amazon Quick AI Agents Vulnerability Allows Unauthorized Access

A security flaw in Amazon Quick's AI Chat Agents enables restricted users to bypass administrative controls and interact with AI agents. Discovered by Fog Security, the issue stems from missing server-side authorization checks in the Chat Agent API. This flaw allows unauthorized access despite explicit restrictions set by administrators. AWS has not publicly acknowledged the issue, classifying it as 'none' and failing to notify customers. The vulnerability is limited to intra-account access, meaning it does not allow cross-tenant access. Organizations using Amazon Quick, particularly those restricting AI functionalities, are affected. The flaw highlights a significant gap between user interface restrictions and backend enforcement in cloud services. No CVEs have been assigned yet, and AWS has not provided a patch or advisory.

Key Points: • Unauthorized access to AI Chat Agents due to missing server-side checks. • AWS classified the issue as 'none' and did not notify affected customers. • The vulnerability impacts organizations using Amazon Quick with restricted AI functionalities.
