What is CVE-2026-32847?

DeepCode contains a path traversal vulnerability located in the SPA catch-all route within new_ui/backend/main.py. This flaw allows unauthenticated users to exploit the system by providing percent-encoded path segments via the GET /{full_path:path} endpoint. By circumventing Starlette's path normalization, attackers can manipulate the paths to traverse outside of the designated FRONTEND_DIST directory. This exploitation may lead to unauthorized access to sensitive files, including SSH private keys, TLS certificates, and application secrets, all through a simple HTTP request.
