CVE-2026-86830

What it is

Incorrect privilege assignment in Temporary Elevated Access Management (TEAM) for AWS IAM Identity Center solution before version 1.5.1 might allow an authenticated remote user with application-level access to read, approve, modify, or revoke arbitrary access requests, thereby obtaining unintended temporary elevated access to the AWS accounts accessed using the TEAM deployment. This issue has been addressed in TEAM version 1.5.1 or later. We recommend upgrading to the latest version and ensuring any forked or derivative code is patched to incorporate the new fixes.
