  "description": "### Impact\n\nUser 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.\n\n```js\nimport { jsPDF } from \"jspdf\";\nconst doc = new jsPDF();\n// Payload:\n// 1. ) closes the JS string.\n// 2. > closes the current dictionary.\n// 3. /AA ... injects an \"Additional Action\" that executes on focus/open.\nconst maliciousPayload = \"console.log('test');) >> /AA << /O << /S /JavaScript /JS (app.alert('Hacked!')) >> >>\";\n\ndoc.addJS(maliciousPayload);\ndoc.save(\"vulnerable.pdf\");\n```\n\n### Patches\nThe vulnerability has been fixed in jspdf@4.2.0.\n\n### Workarounds\nEscape parentheses in user-provided JavaScript code before passing them to the `addJS` method.\n### References\nhttps://github.com/ZeroXJacks/CVEs/blob/main/2026/CVE-2026-25755.md",
