Severity

8.7 (High) CVSS_V4 - CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N CVSS Calculator

Summary

jsPDF Vulnerable to Denial of Service (DoS) via Unvalidated BMP Dimensions in BMPDecoder

Details

Impact

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);

Patches

The vulnerability has been fixed in jsPDF 4.1.0. Upgrade to jspdf@>=4.1.0.

Workarounds

Sanitize image data or URLs before passing it to the addImage method or one of the other affected methods.
