🚨 Severity: CRITICAL 💡 Vulnerability: Server-Side Request Forgery (SSRF) vulnerabilities in URL handling via Python's standard `urllib`. The application accepted untrusted URLs without ensuring they correspond to a safe scheme (e.g. `http://` or `https://`). Attackers could supply schemes like `file://` to read local files on the server (e.g., `file:///etc/passwd`). 🎯 Impact: Attackers could read local files on the system and potentially reach internal network resources depending on the server configuration. 🔧 Fix: Added robust case-insensitive URL scheme validation checking for `http://` and `https://` prior to issuing requests with `urllib` in `kernel/federation.py`, `kernel/treasury.py`, and `kernel/workspace.py`. Raises `FederationDeliveryError` or `RuntimeError` as appropriate. ✅ Verification: Ran unit tests to verify standard execution and manually tested with `file:///etc/passwd` to ensure the validation immediately fails and raises an exception.
