How to Fix CVE-2025-29907

To remediate this vulnerability, upgrade all affected Jspdf dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

jspdf fixed: 3.0.1 
npm install jspdf@3.0.1
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

npm ls jspdf

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2025-29907, inspect your project dependencies using npm:

npm ls jspdf

Analyze the terminal output to locate any version of Jspdf in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 3.0.1), your application is affected.

Note: The npm ls jspdf command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-400: Uncontrolled Resource Consumption, where the product does not properly control the allocation and maintenance of a limited resource. In Jspdf, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### 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)
