html2pdf.js contains a cross-site scripting vulnerability

html2pdf.js contains a cross-site scripting (XSS) vulnerability when given a text source rather than an element. This text is not sufficiently sanitized before being attached to the DOM, allowing malicious scripts to be run on the client browser and risking the confidentiality, integrity, and availability of the page's data. Example attack vector: import html2pdf from 'html2pdf.js/src/index.js'; const maliciousHTML = '<img src=x onerror="alert(document.cookie)">'; html2pdf(maliciousHTML); // or html2pdf().from(maliciousHTML);
