CVE-2026-14904Network attack vector

Authenticated root file read via symlink replacement

Published Jul 7, 2026 · Updated Jul 7, 2026

Improper link resolution in Research and Engineering Studio on AWS 2026.03 and earlier allows remote authenticated users to read host files. Auth.GetUserPrivateKey follows the caller's ~/.ssh/id_rsa symbolic link, and the root cluster-manager process returns the linked file instead of restricting access to the caller's key. Any authenticated user who can replace that path can retrieve root-readable files, including other users' SSH keys and application secrets.
