OS Command Injection in AWS Research and Engineering Studio Virtual Desktop Session Name Handling
CVE-2026-5707 is an OS command injection vulnerability in AWS Research and Engineering Studio (RES) affecting versions 2025.03 through 2025.12.01. The flaw is caused by unsanitized input in the handling of virtual desktop session names, where attacker-controlled session name data is incorporated into an OS command without proper sanitization. A remote authenticated attacker can supply a crafted session name and trigger arbitrary command execution on the virtual desktop host. Successful exploitation results in command execution with root privileges on that host.
