jsPDF Affected by Stored XMP Metadata Injection (Spoofing & Integrity Violation)

CISA KEV lists vulnerabilities known to be exploited. FIRST EPSS estimates the likelihood of exploitation in the next 30 days. An unavailable score does not mean zero risk.

No exploitation or prediction data is available here for these CVEs. This does not mean they are safe or unlikely to be exploited.

jsPDF is a library to generate PDFs in JavaScript. Prior to 4.1.0, 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. The vulnerability has been fixed in [email protected].

### 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 [email protected] ### 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) ```
