CVE-2026-31938
jsPDF is a library to generate PDFs in JavaScript.
Published Mar 18, 2026 · updated Aug 18, 2026 · parall jspdf
jsPDF is a library to generate PDFs in JavaScript. Prior to version 4.2.1, user control of the argument of the function allows attackers to inject arbitrary HTML (such as scripts) into the browser context the created PDF is opened in. The vulnerability can be exploited in the following scenario: the attacker provides values for the output options, for example via a web interface. These values are then passed unsanitized (automatically or semi-automatically) to the attack victim. The victim creates and opens a PDF with the attack vector using one of the vulnerable method overloads inside their browser. The attacker can thus inject scripts that run in the victims browser context and can extract or modify secrets from this context. The vulnerability has been fixed in jspdf@4.2.1. As a workaround, sanitize user input before passing it to the output method.
