From 7998c12fc837895c6a26bbfcedc81d69ff43909a Mon Sep 17 00:00:00 2001 From: Claude Date: Tue, 16 Jun 2026 05:50:53 +0000 Subject: [PATCH 1/3] Implement C-043: release-gate CVE check via pip-audit Add a pip-audit step to the publish workflow that audits dfetch's runtime dependencies against the OSV database before the build proceeds; the workflow fails if any known vulnerability is found. Update compliance_data.py to mark SO.VulnerabilityManagementProcess as implemented (was partially-implemented), add C-043 to its controls, and remove the now-resolved gap note. Regenerate the OSCAL component definition to reflect the new status. Update compliance_track.rst and control_register.rst to remove the "planned CI addition" language and show ECR-A as fully implemented. https://claude.ai/code/session_01EoHvc3bxdr9rpkKHGcpqdr --- .github/workflows/python-publish.yml | 5 +++++ CHANGELOG.rst | 2 ++ doc/explanation/compliance_track.rst | 6 +++--- doc/explanation/control_register.rst | 2 +- security/compliance_data.py | 17 ++++++++------- security/dfetch.component-definition.json | 26 ++++++++--------------- 6 files changed, 29 insertions(+), 29 deletions(-) diff --git a/.github/workflows/python-publish.yml b/.github/workflows/python-publish.yml index ae058b519..16850b57c 100644 --- a/.github/workflows/python-publish.yml +++ b/.github/workflows/python-publish.yml @@ -37,6 +37,7 @@ jobs: fulcio.sigstore.dev:443 rekor.sigstore.dev:443 tuf-repo-cdn.sigstore.dev:443 + api.osv.dev:443 - uses: actions/checkout@df4cb1c069e1874edd31b4311f1884172cec0e10 # v6.0.3 with: @@ -48,6 +49,10 @@ jobs: python-version: '3.x' - name: Install dependencies run: python -m pip install .[wheel] + - name: Audit runtime dependencies for CVEs (C-043) + run: | + pip install pip-audit + pip-audit --vulnerability-service osv - name: Build a binary wheel and a source tarball run: python3 -m build - name: Generate SBOM for Python distribution diff --git a/CHANGELOG.rst b/CHANGELOG.rst index d01a16535..af370e343 100644 --- a/CHANGELOG.rst +++ b/CHANGELOG.rst @@ -1,6 +1,8 @@ Release 0.15.0 (unreleased) ============================ +* Implement C-043: add ``pip-audit`` OSV gate to the release workflow; publishing is blocked if + any known vulnerability is found in dfetch's runtime dependencies * Add CRA Compliance Track B: OSCAL 1.1.2 Component Definition mapping all CRA Annex I Part I essential requirements (ECR-a–m) through prEN 40000-1-4 Security Objectives to dfetch controls; covers Part II via prEN 40000-1-3; introduces controls C-043 (release-gate CVE check), C-044 diff --git a/doc/explanation/compliance_track.rst b/doc/explanation/compliance_track.rst index 9f5881c7a..fc8797dee 100644 --- a/doc/explanation/compliance_track.rst +++ b/doc/explanation/compliance_track.rst @@ -120,9 +120,9 @@ The table below summarises dfetch's implementation of each prEN 40000-1-4 Securi - Status * - **ECR-A** — Be made available on the market without known exploitable vulnerabilities. - SO.VulnerabilityManagementProcess - - :ref:`C-015 `, :ref:`C-016 `, :ref:`C-017 `, :ref:`C-022 ` - - No CVE gate at release time (→ :ref:`C-043 ` planned) - - ⚠ Partial + - :ref:`C-015 `, :ref:`C-016 `, :ref:`C-017 `, :ref:`C-022 `, :ref:`C-043 ` + - — + - ✓ Implemented * - **ECR-B** — Be made available on the market with a secure by default configuration, including the possibility to reset the product to its original state. - SO.SecureDefaultConfiguration - :ref:`C-001 `, :ref:`C-002 ` diff --git a/doc/explanation/control_register.rst b/doc/explanation/control_register.rst index 1346d830a..c12825c5c 100644 --- a/doc/explanation/control_register.rst +++ b/doc/explanation/control_register.rst @@ -201,7 +201,7 @@ requirements not independently surfaced by the risk analysis.
