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

• npm @eigenpal/docx-editor-core: < 1.8.3 → fixed in 1.8.3 • npm @eigenpal/docx-editor-react: < 1.8.3 → fixed in 1.8.3

Summary Embedded font-family names (`word/fontTable.xml`) were interpolated unescaped into an injected `@font-face` `` and into the print window's `document.write()`. A crafted name injects page-wide CSS on open, and breaks out of `` into executable HTML on Print. Impact Opening a crafted `.docx` applies attacker-controlled CSS page-wide with zero clicks (overlay/phishing, attribute-selector exfiltration of input values, tracking beacons). Clicking Print escalates to script execution in the embedder's origin. Remediation Upgrade to 1.8.3. Font names are CSS-escaped before interpolation (quotes, backslash, ``, and CSS newlines), and the print window is assembled with DOM APIs instead of `document.write`.
