How widely exploitable is this vulnerability?

Exploitability depends on how an application integrates Signify. If remote users can influence the signed data or contextual information that Signify evaluates and the application uses that output for access control, the vulnerability may be remotely exploitable.

Does an attacker need valid credentials or a specific role to exploit this?

Not necessarily. The primary requirement is the ability to supply or manipulate data passed into Signify. In some deployments, this may be available to unauthenticated users; in others, a low-privileged account or limited interface access may be required.

What is the safest general fix pattern?

Treat Signify strictly as a data-validation and integrity-checking component, and ensure that actual authorization and privilege decisions are handled by dedicated, explicit access-control logic. Apply strong validation to inputs and ensure that any derived context cannot silently grant higher privileges.
