Is this vulnerability remotely exploitable?

Yes, in scenarios where an attacker can supply data that an application later uses to build PDFs via vulnerable jsPDF Acroform APIs. The attacker typically needs a way to control option labels, appearance states, or similar fields that are passed into those APIs.

What level of access does an attacker need?

The attacker must be able to influence the data passed into jsPDF's Acroform methods, such as through form inputs, configuration dashboards, template editors, or APIs that ultimately feed into PDF generation. Direct access to the PDF generation code is not required; control over its inputs is sufficient.

What is the safest general fix pattern?

Restrict Acroform-related inputs to vetted, strongly typed values controlled by the application, and prevent arbitrary strings from being used as structural parts of the PDF. In addition, ensure that any dynamic content is correctly encoded for the PDF context so it cannot alter document structure or introduce actions.
