How broadly exploitable is this vulnerability?

Exploitability depends on how the application uses jsPDF. If untrusted users can influence AcroForm-related properties without sanitization, they may craft PDFs that contain malicious objects or JavaScript. The actual impact also depends on the PDF viewer's support for and configuration of embedded scripts.

Does an attacker need authenticated access to exploit this issue?

Not necessarily. Any context where an attacker can provide data that flows into vulnerable jsPDF AcroForm APIs can be abused, whether or not that context requires authentication. In many real deployments, such access may be tied to user accounts or submission forms, so the effective access level varies by application.

What is the safest general fix pattern?

Constrain and sanitize all data used in AcroForm configuration so only benign, expected values are permitted and ensure that user input cannot control low-level PDF object structure or action definitions. Using centralized sanitization/encoding utilities for all PDF-related output is typically the most robust pattern.
