A critical vulnerability exists in Loom for AWS prior to version 1.6.1, allowing remote attackers to gain super-admin access to the agent control plane due to missing authentication in the application API. This flaw enables unauthorized actions such as registering tool servers, accessing stored integration credentials, and modifying IAM role policies. Organizations using Loom for AWS without an identity provider configured must prioritize upgrading to version 1.6.1 or later to mitigate this severe risk.

Original NVD Description

Missing authentication for critical function in the authentication dependency in Loom for AWS before 1.6.1 allowed remote actors to obtain super-admin authority over the agent control plane, including registering tool servers, reading stored integration credentials, and rewriting the IAM role policies attached to managed agent roles, via any request to the application API in a deployment where no identity provider is configured. To remediate this issue, users should upgrade to version 1.6.1 or later.
