Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Sandbox Escape: Untrusted agent code executing within the QuickJS REPL sandbox could leverage dangerous built-in VFS file system globals (readFile/writeFile) to access or modify arbitrary files on the host system. Developers must ensure these globals are completely stripped from the sandbox environment.
Auth Bypass: Failing to enforce filesystem middleware permissions (read, write, edit rules) combined with absolute path validation allows agents to bypass intended workspace boundaries and access unauthorized directories.
Path Traversal: Insufficiencies in file path resolution allow path traversal sequences, tilde expansion, and platform-specific absolute paths to escape designated workspaces. Rigid canonicalization and prefix checks are required to prevent reading or writing sensitive host files.
