How exploitable is this vulnerability in practice?

Exploitability is high when attackers can access JWT verification endpoints without strict rate limiting or monitoring. Because the JWT secret is derived from the admin's password using MD5, an attacker who can perform many verification attempts can systematically brute-force the password and gain administrative access.

What level of access does an attacker need to exploit this?

Typically, only network access to the affected DataEase instance and the relevant JWT validation endpoints is required. The attacker does not need valid credentials initially, as they are attempting to recover the admin's password via brute force.

What is the safest general fix pattern?

The safest approach is to completely separate user passwords from JWT signing keys. Use a randomly generated, high-entropy server-side secret (or keys managed by a dedicated key management system) for JWT signing, and handle user passwords exclusively via secure password hashing for verification.
