What is CVE-2025-2887?

The Tough client by AWS contains a vulnerability that arises during the process of rolling back to a target. This flaw prevents the client from accurately detecting the rollback for delegated targets, potentially allowing the client to retrieve a target from an incorrect source. As a result, this could lead to unintended alterations in the contents of the target. To mitigate this risk, users are urged to upgrade to Tough version 0.20.0 or later and ensure that any forked or derivative code is updated with the latest patches to incorporate the necessary fixes.
