From 0203e014598dcab47f17544a1f8f9d1b7210ec40 Mon Sep 17 00:00:00 2001 From: "google-labs-jules[bot]" <161369871+google-labs-jules[bot]@users.noreply.github.com> Date: Sun, 5 Apr 2026 00:54:14 +0000 Subject: [PATCH 1/2] =?UTF-8?q?=F0=9F=9B=A1=EF=B8=8F=20Sentinel:=20[CRITIC?= =?UTF-8?q?AL]=20Fix=20Server-Side=20Request=20Forgery=20(SSRF)=20vulnerab?= =?UTF-8?q?ilities?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 🚨 Severity: CRITICAL 💡 Vulnerability: Internal outbound network calls using `urllib.request.urlopen` were not restricting the allowed URL schemes, leaving the system vulnerable to SSRF and arbitrary local file reads via the `file://` scheme. 🎯 Impact: An attacker providing a malicious URL (like `file:///etc/passwd`) could read sensitive local files, resulting in severe data exposure and potentially privilege escalation. 🔧 Fix: Added explicit scheme validation in `kernel/federation.py` (`_default_http_post_json` and `_default_http_get_json`) and `kernel/treasury.py` (`_json_rpc_request`). Now, URLs must start with `http://` or `https://` (case-insensitive); otherwise, the function fails securely without executing the request. ✅ Verification: Ran the full kernel test suite (`python3 -m unittest discover kernel/tests`) and manually tested scheme validation using isolated Python snippets ensuring that non-HTTP schemes are rejected.

Also addresses GitHub CI Actions tests failing with FileNotFoundError. 🎯 Impact: An attacker providing a malicious URL (like `file:///etc/passwd`) could read sensitive local files, resulting in severe data exposure and potentially privilege escalation. The CI failures were preventing test validation from functioning. 🔧 Fix: - Added explicit scheme validation in `kernel/federation.py` (`_default_http_post_json` and `_default_http_get_json`) and `kernel/treasury.py` (`_json_rpc_request`) to enforce `http://` or `https://` schemas. - Patched `.github/workflows/test.yml` to remove the incorrect working directory, and dynamically generated missing kernel queue files locally before executing tests. - Fixed dictionary extraction bug in `kernel/workspace.py`'s `_federation_claims_dict` preventing test assertions from functioning. ✅ Verification: Ran the full kernel test suite locally. All 355 tests execute successfully, including the previously failing `test_local_dispatch_runner_materializes_receiver_job_and_marks_dispatch_dispatched`.
