CVE-2026-31898
March 18, 2026
jsPDF is a library to generate PDFs in JavaScript. Prior to version 4.2.1, user control of arguments of the "createAnnotation" method allows users to inject arbitrary PDF objects, such as JavaScript actions. If given the possibility to pass unsanitized input to the following method, a user can inject arbitrary PDF objects, such as JavaScript actions, which might trigger when the PDF is opened or interacted with the "createAnnotation": "color" parameter. The vulnerability has been fixed in jsPDF@4.2.1. As a workaround, sanitize user input before passing it to the vulnerable API members.
