• Severity: high (CVSS 7.5 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.4% probability of exploitation in the next 30 days

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.
