Local AI agent in DWN.BRIDGE could read files outside its workspace

A community member found that the local web-session agent in DWN.BRIDGE could read files outside its workspace, such as C:\Windows\System32\drivers\etc\hosts, by directly invoking the READFILE tool.
The author says they patched the client to canonicalize paths, enforce the active workspace root, and block absolute paths or directory traversal attempts. If the agent tries to escape the sandbox, the app now raises a security alert. The post frames this as a broader question for local AI dev tools: how to balance agent autonomy with OS and filesystem safety.
