Is this vulnerability remotely exploitable over the network?

Yes, if an attacker can access any JimuReport interface or API that allows them to define or influence H2 JDBC URLs, they can exploit this issue remotely whenever the application uses that connection string.

Does an attacker need valid credentials or admin access?

It depends on how JimuReport is deployed. If only privileged administrators can edit H2 data source configurations, an attacker would typically need those credentials. In less restricted deployments where lower-privilege users can define data sources, the bar for exploitation is lower.

What is the safest general fix pattern?

The safest pattern is to remove or strictly restrict user control over JDBC URLs, especially for H2. Compose connection strings entirely on the server from vetted components, enforce strict URL templates, and disable or avoid database driver features that can execute code or load external resources.
