How broadly exploitable is this vulnerability?

Exploitability depends on how the ERP instance is exposed. If the affected endpoints are reachable from the internet or from large internal networks, an attacker with only network access may be able to retrieve documents they are not authorized to see.

Does an attacker need a valid account to exploit this?

Not necessarily. Because some endpoints lack proper authentication or authorization checks, it may be possible to access documents without any account or with a low-privileged account that should not have visibility into the targeted information.

What is the safest general fix pattern for developers?

Centralize access control by enforcing authentication and authorization for all document-related routes through a shared middleware or policy layer. Each request to a document must verify the user's identity and confirm that the user is allowed to access that specific document before any content is returned.
