GHSA-x7m8-jrm8-hpvx: @eigenpal/docx-editor-react: CSS injection and print-time XSS via unescaped embedded font-family name

September 10, 2026

Embedded font-family names (word/fontTable.xml) were interpolated unescaped into an injected @font-face <style> and into the print window’s document.write(). A crafted name injects page-wide CSS on open, and breaks out of <style> into executable HTML on Print.
