The library runs in Node.js environments and is commonly used to programmatically generate PDFs.", "description_and_impact": "A flaw in the AcroForm module of the jsPDF library enables an attacker to inject arbitrary PDF objects, including JavaScript actions, through uncontrolled user\u2011supplied input. When a user loads the impacted PDF and hovers over a radio button, the embedded JavaScript executes, potentially allowing full code execution within the PDF viewer. This vulnerability is identified as CWE\u2011116, an input/output communication error that permits unauthorized code execution.", "risk_and_exploitability": "The CVSS score of 8.1 signals a high severity condition, while the EPSS score of less than 1% suggests a low probability of active exploitation at present. The vulnerability is not listed in the CISA KEV catalog. Exploitation requires a user to open the malicious PDF in a renderer that honors embedded JavaScript and to hover over a radio button, so the attack vector is client\u2011side and needs user interaction to trigger the payload."}}}}, "created": "2026-02-20T10:06:29.062291+00:00", "updated": "2026-04-17T18:15:26.770923+00:00", "vendors": ["parall", "parall$PRODUCT$jspdf"]}
