Root Cause Analysis

The vulnerability stems from static HTML template files (pdoc/templates/math.html.jinja2) embedding a polyfill.io script reference, not from specific code functions. The malicious CDN link was hardcoded in template markup rather than being dynamically generated by programmatic functions. The fix involved removing these static script references from template files, with no actual code functions modified in the commit diff. While math mode activation (--math flag) triggers template usage, the vulnerability itself resides in template content rather than executable functions.
