CVE-2026-14904
Bulletin ID: 2026-053-AWS Scope: AWS Content Type: Important (requires attention) Publication Date: 07/07/2026 09:45 AM PDT Description: AWS Research and Engineering Studio (RES) is an open-source solution that enables researchers and engineers to create and manage secure virtual desktops and computing resources on AWS. We identified an improper link resolution before file access issue (CWE-59) in the Auth.GetUserPrivateKey API. An authenticated remote user could read arbitrary files on the cluster-manager EC2 instance by replacing their SSH private key file (~/.ssh/id_rsa) with a symbolic link targeting any file on the host. Because the cluster-manager process runs as root, any file readable by root is exposed, including other users' SSH private keys and application configuration secrets. Impacted versions: <=2026.03 Please refer to the article below for the most up-to-date and complete information related to this AWS Security Bulletin.
