How widely exploitable is this vulnerability?

Exploitability depends on whether your application passes user-controlled or externally sourced data into `addJS` and then distributes the resulting PDFs. If `addJS` is only used with static, hardcoded scripts and no user input, the practical risk is significantly reduced.

Does an attacker need direct access to the server to exploit this issue?

No. An attacker generally only needs a way to influence the value passed to `addJS`—for example, by submitting crafted form data or API requests that your application then embeds into the PDF. They do not need system-level access to the server running jsPDF.

What is the safest general fix pattern?

The safest approach is to avoid embedding user-supplied content in `addJS` entirely. If dynamic behavior is absolutely necessary, enforce strict validation and escaping of input (such as reliably escaping parentheses and other control characters) and restrict scripts to a predefined, minimal set of safe operations.
