Very low probability of exploitation
EPSS predicts the probability of exploitation in the next 30 days based on real-world threat data, complementing CVSS severity scores with actual risk assessment.
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.
