Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

CVE-2026-22787

High
8.7/10

Summary

html2pdf.js converts any webpage or element into a printable PDF entirely client-side. In versions 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.

CWE-79 - Cross Site Scripting

Cross-Site Scripting, commonly referred to as XSS, is the most dominant class of vulnerabilities. It allows an attacker to inject malicious code into a pregnable web application and victimize its users. The exploitation of such a weakness can cause severe issues such as account takeover, and sensitive data exfiltration. Because of the prevalence of XSS vulnerabilities and their high rate of exploitation, it has remained in the OWASP top 10 vulnerabilities for years.
