Reporting a Vulnerability

If you discover a security issue in this template, please report it privately rather than opening a public issue:

Please include reproduction steps and the affected file or route. We aim to acknowledge reports within a few days.

Scope

This repository is a static Astro site deployed to GitHub Pages (output: 'static'). There is no application server, no database, and no runtime request handling under our control. Build-time scripts in scripts/src/ run on trusted developer and CI machines using repo-committed inputs.

In-CI Security Tooling

Every pull request runs the following gates (see .github/workflows/ci.yml):

  • Dependency auditpnpm run audit:ci (pnpm audit --prod filtered through .audit-allowlist.json, which documents and time-bounds each accepted transitive advisory).
  • Trivy — filesystem SBOM scan, results uploaded as SARIF.
  • Semgrep — SAST (p/javascript, p/typescript, p/secrets). See ADR-046.
  • gitleaks — secret scanning, configured by .gitleaks.toml.

Known Not-Applicable Findings

Automated scanners run against the public *.github.io URL routinely surface the following. They are not fixable from this repository and are documented here so they are not refiled:

  • TLS cipher suites without forward secrecy. TLS termination for *.github.io is managed entirely by GitHub. Cipher policy is not configurable from this repo, and forward-secret (ECDHE) ciphers are already offered alongside the flagged legacy suites.
  • "HTTP Basic Auth brute-force success." GitHub Pages serves no HTTP Basic Auth on this site. Tools such as hydra interpret the unconditional 200 response to any request as an authentication success; there is no credential to compromise.

These were both reported by an automated assessment on 2026-05-21 and confirmed not-applicable on review.
