How to Fix CVE-2026-24043

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: 4.1.0 
npm install jspdf@4.1.0
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-2026-24043, 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 4.1.0), 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-20: Improper Input Validation, where the product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. 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 `addMetadata` function allows users to inject arbitrary XML. If given the possibility to pass unsanitized input to the `addMetadata` method, a user can inject arbitrary XMP metadata into the generated PDF. If the generated PDF is signed, stored or otherwise processed after, the integrity of the PDF can no longer be guaranteed. Example attack vector: ```js import { jsPDF } from "jspdf" const doc = new jsPDF() // Input a string that closes the current XML tag and opens a new one. // We are injecting a fake "dc:creator" (Author) to spoof the document source. const maliciousInput = '</jspdf:metadata></rdf:Description>' + '<rdf:Description xmlns:dc="http://purl.org/dc/elements/1.1/">' + '<dc:creator>TRUSTED_ADMINISTRATOR</dc:creator>' + // <--- Spoofed Identity '</rdf:Description>' + '<rdf:Description><jspdf:metadata>' // The application innocently adds the user's input to the metadata doc.addMetadata(maliciousInput, "http://valid.namespace") doc.save("test.pdf") ``` ### Patches The vulnerability has been fixed in jsPDF@4.1.0 ### Workarounds Sanitize user input before passing it to the `addMetadata` method: escape XML entities. For example: ```js let input = "..." input = input .replace(/&/g, "&amp;") .replace(/</g, "&lt;") .replace(/>/g, "&gt;") .replace(/"/g, "&quot;") .replace(/'/g, "&apos;") doc.addMetadata(input) ```
