jsPDF has a PDF Injection in AcroFormChoiceField which allows Arbitrary JavaScript Execution

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 properties and methods of the Acroform module allows users to inject arbitrary PDF objects, such as JavaScript actions. If given the possibility to pass unsanitized input to one of the following methods or properties, a user can inject arbitrary PDF objects, such as JavaScript actions, which are executed when the victim opens the document. The vulnerable API members are AcroformChoiceField.addOption, AcroformChoiceField.setOptions, AcroFormCheckBox.appearanceState, and AcroFormRadioButton.appearanceState. The vulnerability has been fixed in [email protected].

### Impact User control of properties and methods of the Acroform module allows users to inject arbitrary PDF objects, such as JavaScript actions. If given the possibility to pass unsanitized input to one of the following methods or properties, a user can inject arbitrary PDF objects, such as JavaScript actions, which are executed when the victim opens the document. The vulnerable API members are: * `AcroformChoiceField.addOption` * `AcroformChoiceField.setOptions` * `AcroFormCheckBox.appearanceState` * `AcroFormRadioButton.appearanceState` Example attack vector: ```js import { jsPDF } from "jspdf" const doc = new jsPDF(); var choiceField = new doc.AcroFormChoiceField(); choiceField.T = "VulnerableField"; choiceField.x = 20; choiceField.y = 20; choiceField.width = 100; choiceField.height = 20; // PAYLOAD: // 1. Starts with "/" to bypass escaping. // 2. "dummy]" closes the array. // 3. "/AA" injects an Additional Action (Focus event). // 4. "/JS" executes arbitrary JavaScript. const payload = "/dummy] /AA << /Fo << /S /JavaScript /JS (app.alert('XSS')) >> >> /Garbage ["; choiceField.addOption(payload); doc.addField(choiceField); doc.save("test.pdf"); ``` ### Patches The vulnerability has been fixed in [email protected]. ### Workarounds Sanitize user input before passing it to the vulnerable API members. ### Credits Research and fix: Ahmet Artuç
