User control of the first argument of the addImage method results in Denial of Service.
If given the possibility to pass unsanitized image data or URLs to the addImage method, a user can provide a harmful BMP file that results in out of memory errors and denial of service. Harmful BMP files have large width and/or height entries in their headers, wich lead to excessive memory allocation.
Other affected methods are: html.
Example attack vector:
import { jsPDF } from "jspdf"
// malicious BMP image data with large width/height headers
const payload = ...
const doc = new jsPDF();
doc.addImage(payload, "BMP", 0, 0, 100, 100);
The vulnerability has been fixed in jsPDF 4.1.0. Upgrade to jspdf@>=4.1.0.
Sanitize image data or URLs before passing it to the addImage method or one of the other affected methods.
