Recurring patterns

The bug types that recur here, drawn from past fixes, not open vulnerabilities.

Sandbox Escape: The guest Node.js execution runtime is susceptible to sandbox escape and host module fall-through via relative symlink traversal and improper ESM module resolution boundaries. Developers must ensure relative paths are fully resolved and symlinks are evaluated prior to any boundary checking.

Sandbox Escape: Bypasses in the guest runtime isolation allow unauthorized network egress via ambient fetch and path-traversal in storage namespacing. Securing this requires strict shadowing of globals and hardening permission-validation regexes against bracket-notation or string-concatenation obfuscation.

SSRF: Missing host and port properties in the network adapter's policy callbacks can allow guest network requests to bypass host-keyed filters, potentially leading to unauthorized authenticated actions using the embedding page's ambient credentials.
