Privilege Escalation in AWS Research and Engineering Studio Session Creation
CVE-2026-5708 is a privilege-escalation vulnerability in the session creation component of AWS Research and Engineering Studio (RES) affecting versions prior to 2026.03. The flaw stems from improper control of user-modifiable attributes during session creation, described as unsanitized control of user-modifiable attributes. An authenticated remote attacker can send a crafted API request to manipulate those attributes and cause RES to grant access associated with the Virtual Desktop Host instance profile. This can extend the attacker's effective permissions beyond their intended role and enable interaction with additional AWS resources and services reachable through that instance profile.
