Security Policy

Scope

This repository ships static HTML / CSS / JS wizards. There is no backend, no server-side state, and no authentication. The realistic risk surface is:

  • Cross-site scripting via user-imported JSON state.
  • Supply-chain tampering with the vendored jspdf.umd.min.js.
  • Content spoofing via a malicious fork hosted elsewhere.

Supported versions

Only the main branch is supported. Once the project is donated to CoSAI, this section will describe the accepted-release cadence.

Reporting a vulnerability

Please do not open a public issue for suspected vulnerabilities.

  1. Open a private GitHub Security Advisory on this repository, or
  2. Email the maintainer with a clear reproduction and the branch / commit SHA.

You should receive acknowledgement within 5 business days. We aim to publish a fix (or a documented mitigation) within 30 days of acknowledgement for issues we can reproduce.

Third-party components

The only bundled third-party runtime dependency is jsPDF 2.5.1, served locally from /shared/vendor/jspdf.umd.min.js. The expected SHA-256 is pinned in NOTICE:

98ccf17aa10c20bb1301762618fcc9b6ab3a4e7f26b6071d64d0b41154df3875

If you are redistributing this project, verify the hash matches before publishing. The GitHub Actions secret-scan workflow runs gitleaks over full history (fetch-depth: 0) to guard against accidental credential exposure.

Privacy

The wizards never transmit user inputs. State is persisted in localStorage on the viewer's own device and can be deleted by clearing site data. JSON export / import is client-only.
