From 3081d352b2e52d66839b61acb7528f123d4bf6f0 Mon Sep 17 00:00:00 2001 From: PythonWoods-Dev Date: Thu, 16 Apr 2026 11:28:10 +0200 Subject: [PATCH] =?UTF-8?q?fix(shield)!:=20Obsidian=20Bastion=20Hardened?= =?UTF-8?q?=20(v0.6.1rc2)=20=E2=80=94=20security=20seal?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This release seals the Bastion against findings from Operation Obsidian Stress. Security Hardening: - ZRT-006: Shield normalizer now strips Unicode category Cf (zero-width chars) and decodes HTML entities. - ZRT-007: Added 1-line lookback buffer and HTML/MDX comment stripping for token-interleaving bypass protection. - CI/CD: Hardened GitHub Actions to v4/v6 stable and setup-uv@v7. Technical Fixes: - Restored historical CHANGELOG headers (v0.6.1rc1) corrupted by automation. - Hardened bump-my-version regex to target only primary headers (## prefix). - Resolved JSON exit-code asymmetry in orphan and asset checks. - Added gitlab-pat to the Shield family suite (9 families total). Tests: 1046 passed (83 new regression tests included). --- .github/workflows/secret-scan.yml | 3 + CHANGELOG.it.md | 21 ++ CHANGELOG.md | 19 + CITATION.cff | 4 +- CONTRIBUTING.md | 1 + README.it.md | 8 +- README.md | 8 +- RELEASE.md | 48 +-- examples/vcs-aware-project/README.md | 2 +- pyproject.toml | 20 +- src/zenzic/__init__.py | 2 +- src/zenzic/cli.py | 2 +- src/zenzic/core/scanner.py | 9 +- src/zenzic/core/shield.py | 88 ++++- tests/test_blue_i18n_edge.py | 259 ++++++++++++++ tests/test_blue_vsm_edge.py | 220 ++++++++++++ tests/test_shield_obfuscation.py | 507 +++++++++++++++++++++++++++ uv.lock | 2 +- 18 files changed, 1177 insertions(+), 46 deletions(-) create mode 100644 tests/test_blue_i18n_edge.py create mode 100644 tests/test_blue_vsm_edge.py create mode 100644 tests/test_shield_obfuscation.py diff --git a/.github/workflows/secret-scan.yml b/.github/workflows/secret-scan.yml index 9dc40c4..76c7b28 100644 --- a/.github/workflows/secret-scan.yml +++ b/.github/workflows/secret-scan.yml @@ -8,6 +8,9 @@ on: pull_request: branches: [ main ] +permissions: + contents: read + jobs: secret-scan: name: Native GitHub Secret Scan Proxy diff --git a/CHANGELOG.it.md b/CHANGELOG.it.md index 989b885..ac72242 100644 --- a/CHANGELOG.it.md +++ b/CHANGELOG.it.md @@ -11,6 +11,27 @@ Le versioni seguono il [Semantic Versioning](https://semver.org/). ## [Non rilasciato] +## [0.6.1rc2] — 2026-04-16 — Obsidian Bastion (Hardened) + +### SICUREZZA: Risultati Operation Obsidian Stress + +- **Shield: bypass tramite caratteri Unicode di formato (ZRT-006).** Caratteri + Unicode invisibili (ZWJ U+200D, ZWNJ U+200C, ZWSP U+200B) inseriti all'interno + di un token potevano eludere il pattern matching.
