CVE-2026-32847

Full vulnerability record from the local CVENow database.

Description

DeepCode through commit c991dc2 contains a path traversal vulnerability in the SPA catch-all route in new_ui/backend/main.py that allows unauthenticated attackers to read arbitrary files by supplying percent-encoded path segments to the GET /{full_path:path} endpoint. Attackers can bypass Starlette's path normalization by encoding slashes as %2F and dots as %2E%2E, causing the joined path to traverse outside FRONTEND_DIST and exposing sensitive files such as SSH private keys, TLS certificates, and application secrets with a single HTTP request.

Los atacantes pueden eludir la normalización de rutas de Starlette codificando las barras diagonales como %2F y los puntos como %2E%2E, haciendo que la ruta unida se desplace fuera de FRONTEND_DIST y exponiendo archivos sensibles como claves privadas SSH, certificados TLS y secretos de aplicación con una única solicitud HTTP."
