CVE-2026-25535

Description

### 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 GIF file that results in out of memory errors and denial of service. Harmful GIF 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 GIF image data with large width/height headers const payload = ... const doc = new jsPDF(); doc.addImage(payload, "GIF", 0, 0, 100, 100); ``` ### Patches The vulnerability has been fixed in jsPDF 4.1.1. Upgrade to jspdf@>=4.2.0. ### Workarounds Sanitize image data or URLs before passing it to the addImage method or one of the other affected methods. ### References https://github.com/ZeroXJacks/CVEs/blob/main/2026/CVE-2026-25535.md
