ToolShell — SharePoint Zero-Day Presentation

A Marp slide deck about CVE-2025-53770, with each slide kept in its own file under slides/.

Build

./build.sh           # assemble slides into presentation.md
./build.sh html      # + render presentation.html
./build.sh pdf       # + render presentation.pdf
./build.sh all       # + HTML, PDF, and PNG preview of every slide

The script uses npx to fetch @marp-team/marp-cli on demand — no global install required.

Add a new slide

1. Create the slide file, e.g. slides/16-new-slide.md:

   # My Title
   
   <h2><span class="pill-tag">Section</span>Sub headline</h2>
   
   <div class="grid-2">
     <div class="tile"><h3>Card A</h3><p>...</p></div>
     <div class="tile pink"><h3>Card B</h3><p>...</p></div>
   </div>

2. Reference it in presentation.template.md at the right position:

   ---
   
   @@INCLUDE:slides/16-new-slide.md@@

3. Rebuild:

   ./build.sh all

Available CSS classes

Look at existing slides for examples — the theme provides tile, grid-2/3, term, score-card, flow, compare, measure, lesson, pill-tag, chip, plus body classes title, hero, end for full-bleed layouts.
