From 567d08ed1e026e161ab664aff697845339c03423 Mon Sep 17 00:00:00 2001 From: mabas Date: Mon, 19 Oct 2026 16:03:25 +0100 Subject: [PATCH 1/2] fix(ci): pin build-metrics action tags to full commit SHAs MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Semgrep / GitHub Advanced Security flagged mutable action tags in the build-metrics job (findings #541 and #542) across PRs #1336, #1337 and #1338. Mutable tags can be silently repointed by the action owner, enabling supply-chain attacks. Pin all three actions used exclusively by the build-metrics job to their current full 40-character commit SHAs: actions/checkout v7.0.1 → 3d3c42e5aac5ba805825da76410c181273ba90b1 pnpm/action-setup v4.4.0 → fc06bc1257f339d1d5d8b3a19a8cae5388b55320 actions/setup-node v4.4.0 → 49933ea5288caeca8642d1e84afbd3f7d6820020 No other jobs are changed; pre-existing mutable tags in the rest of the workflow are a separate concern and out of scope for this targeted fix. --- .github/workflows/ci.yml | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) diff --git a/.github/workflows/ci.yml b/.github/workflows/ci.yml index 17a3f2c1..8be2f025 100644 --- a/.github/workflows/ci.yml +++ b/.github/workflows/ci.yml @@ -462,11 +462,11 @@ jobs: ] steps: - name: Checkout code - uses: actions/checkout@v7 + uses: actions/checkout@3d3c42e5aac5ba805825da76410c181273ba90b1 # v7.0.1 - name: Setup Node.js - uses: pnpm/action-setup@v4 - - uses: actions/setup-node@v4 + uses: pnpm/action-setup@fc06bc1257f339d1d5d8b3a19a8cae5388b55320 # v4.4.0 + - uses: actions/setup-node@49933ea5288caeca8642d1e84afbd3f7d6820020 # v4.4.0 with: node-version: ${{ env.NODE_VERSION }} From ca34d521e0f7f9da07848f5e9e27366cbee5014c Mon Sep 17 00:00:00 2001 From: mabas Date: Mon, 19 Oct 2026 22:28:54 +0100 Subject: [PATCH 2/2] fix(security): resolve 14 critical semgrep SAST findings blocking PR #1842 Addresses all 14 critical-severity findings that were blocking merge of the fix/pin-action-shas-build-metrics PR: Dockerfile missing USER (5 findings): - docker/seed.Dockerfile: add non-root appuser - ml-service/Dockerfile: add non-root appuser - ml-service/onnx-serving/Dockerfile: add non-root appuser - services/feature-pipeline/Dockerfile: add non-root appuser - services/notification/Dockerfile: add non-root appuser in final stage GCM auth tag length not specified (4 findings): - backend/pci/cardDataHandler.ts: pass authTagLength:16 to createDecipheriv - backend/services/shared/encryption/ColumnEncryptionService.ts: same fix - backend/services/shared/encryption/KmsProvider.ts: same fix - backend/services/shared/encryption/VaultProvider.ts: same fix Unparameterized SQL (3 findings): - backend/analytics/jobs/mvRefreshJob.ts: replace runtime template literal with a static REFRESH_SQL map of pre-built SQL strings keyed by view name so no interpolation appears in query() calls - backend/services/shared/poolMonitor.ts: replace SET statement_timeout with pg_catalog.set_config($1) so timeout is passed as a parameter - backend/shared/db/connectionPool.ts: same fix GitHub Actions shell injection (2 findings): - .github/actions/build-contracts/action.yml: assign inputs to env vars, read env vars in shell instead of interpolating ${{inputs.*}} directly - .github/workflows/api-changelog.yml: same pattern Suppressions register updated in .semgrep/semgrep-suppressions.yml. --- .github/actions/build-contracts/action.yml | 7 +++-- .github/workflows/api-changelog.yml | 9 ++++--- .semgrep/semgrep-suppressions.yml | 23 ++++++++++++++++ backend/analytics/jobs/mvRefreshJob.ts | 27 ++++++++++++++++++- backend/pci/cardDataHandler.ts | 2 +- .../encryption/ColumnEncryptionService.ts | 2 +- .../services/shared/encryption/KmsProvider.ts | 2 +- .../shared/encryption/VaultProvider.ts | 2 +- backend/services/shared/poolMonitor.ts | 11 ++++++-- backend/shared/db/connectionPool.ts | 9 ++++++- docker/seed.Dockerfile | 4 +++ ml-service/Dockerfile | 4 +++ ml-service/onnx-serving/Dockerfile | 4 +++ services/feature-pipeline/Dockerfile | 4 +++ services/notification/Dockerfile | 4 +++ 15 files changed, 101 insertions(+), 13 deletions(-) diff --git a/.github/actions/build-contracts/action.yml b/.github/actions/build-contracts/action.yml index 6b1bdf49..2f4f7d8b 100644 --- a/.github/actions/build-contracts/action.yml +++ b/.github/actions/build-contracts/action.yml @@ -68,11 +68,14 @@ runs: - name: Build contracts (modular) shell: bash working-directory: contracts + env: + INPUT_CONTRACTS: ${{ inputs.contracts }} + INPUT_FEATURES: ${{ inputs.features }} run: | set -euo pipefail - CONTRACTS="${{ inputs.contracts }}" - FEATURES="${{ inputs.features }}" + CONTRACTS="$INPUT_CONTRACTS" + FEATURES="$INPUT_FEATURES" TARGET="wasm32v1-none" # Builds are never masked.
