From 6e41f09c6e76b280566ae63c43ce4267a7fbf2fd Mon Sep 17 00:00:00 2001 From: Jon Chery Date: Thu, 23 Jul 2026 11:54:58 +0000 Subject: [PATCH] =?UTF-8?q?verify(P43):=20code=20review=20=E2=80=94=201=20?= =?UTF-8?q?P0=20auto-fixed,=201=20P1=20auto-fixed,=203=20P1=20flagged?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ---ci--- phase: 43 milestone: v1.9 status: verify lessons: - P0 fix: run_platform.sh HITL gate passed approver via string interpolation into Python (GITHUB_ACTOR injection vector) — fixed by passing env vars (ACDL_HITL_*) read via os.environ - P1 fix: attestation_matrix._is_fresh accepted future-dated artifacts (negative age bypassed freshness) — fixed with negative-age guard + test - P1 flagged: WizClient._post does not check GraphQL errors (silent empty-list mask) - P1 flagged: WizClient._post no SSRF validation on WIZ_API_URL - P1 flagged: contract_resolver._load_env duplicates environment_check.load (can drift) ---/ci--- Multi-persona review of the v1.9 diff (v1.8.0..HEAD). Review pass 2 (post-complete) caught issues the initial self-review missed: P0-INJECT (auto-fixed): scripts/run_platform.sh Step 7b interpolated $APPROVER (GITHUB_ACTOR/GITEA_ACTOR) directly into a Python string literal — an attacker-controllable username containing shell/python metacharacters would execute arbitrary Python. Fixed: approver, contract id, and env are now passed as environment variables to the subprocess and read via os.environ[...] (no string interpolation). P1-FRESHNESS (auto-fixed): core/attestation_matrix.py _is_fresh accepted future-dated artifacts (negative age.days <= window_days). Fixed: added age.total_seconds() < 0 guard rejecting future timestamps. Test added: test_freshness_rejects_future_dated_artifact. 3 P1 flagged for post-hoc: - WizClient._post does not surface GraphQL errors (silent empty mask) - WizClient._post no SSRF validation on WIZ_API_URL (operator-supplied, low risk) - contract_resolver._load_env duplicates environment_check.load (drift risk) REVIEW.md updated with the findings. 494 tests pass; run_ci.sh + run_platform.sh --check-only green. --- .ciagent/REVIEW.md | 69 +++++++++++++++++++++++++++----- core/attestation_matrix.py | 4 ++ scripts/run_platform.sh | 9 +++-- tests/test_attestation_matrix.py | 7 ++++ 4 files changed, 77 insertions(+), 12 deletions(-) diff --git a/.ciagent/REVIEW.md b/.ciagent/REVIEW.md index 53faba8..79581f1 100644 --- a/.ciagent/REVIEW.md +++ b/.ciagent/REVIEW.md @@ -3,12 +3,16 @@ **Reviewer:** ci-code-reviewer (model: glm-5.2) **Scope:** v1.9 milestone — Phases 39–42 (tags v1.8.1..v1.8.4), diff `v1.8.0..HEAD` **Date:** 2026-07-23 -**Verdict:** **READY TO SHIP** — 0 P0, 0 P1 +**Verdict:** **READY TO SHIP** — 1 P0 auto-fixed, 1 P1 auto-fixed, 3 P1 flagged for post-hoc > **Note (D-086):** This REVIEW.md was reconstructed at v1.9 complete. > The previous content was the v1.2 milestone review (v1.3–v1.8 reviews > were not persisted to this file).
