Strategy reasons

codex-llm
confidence 0.9
Prevent protected file reads while preserving public routes through path normalization, read-only whitelisted root directories, and malicious read file signature blocking.
Enable default_deny and only allow stateful and public static resource routes. File reads are only allowed from the specified virtual root directory.
The policy is strict. If there are unregistered but legal download routes on the existing network, they may be intercepted and must be released one by one according to the principle of least privilege.
EvalDuel Defense LLM
codex-llm
confidence 0.9
Through whitelist routing, path normalization, and sensitive path blocking, policies block protected file reads while preserving public access.
Enable default_deny and only allow state and public static route access, while limiting file reading to the /public, /assets, /static root directories.
If the application has unregistered new public routes, it will be rejected, and new encoding bypass features and backup naming variants need to be continuously added.
