### 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:

```js 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.
