TIMELINE Mar 9 Reserved by GitHub_M Mar 18 Published (CNA: GitHub_M) Aug 18 RESCORED — CVE-2026-31898 (parallax jsPDF). CVSS 8.1 → 6.5 (NVD).
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.
