DescriptionGitHub Advisory

html2pdf.js converts any webpage or element into a printable PDF entirely client-side. Prior to 0.14.0, 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. This vulnerability has been fixed in html2pdf.js@0.14.0.

AnalysisAI

html2pdf.js versions prior to 0.14.0 fail to sanitize text input before inserting it into the DOM, enabling stored or reflected XSS attacks that compromise client-side data confidentiality and integrity. Attackers can inject malicious scripts that execute in users' browsers when the library processes untrusted text sources, and public exploit code is available. Update to version 0.14.0 or later to remediate this vulnerability.
