How exploitable is this vulnerability in real-world deployments?

Exploitability is high wherever an attacker can obtain or abuse an administrator account and the Kanboard server is allowed to download plugins from remote locations. The attack is straightforward once admin access and endpoint knowledge are available.

Does an attacker need administrative access to exploit this issue?

Yes. The vulnerability still requires authenticated administrative privileges; it does not grant access to unauthenticated users, but it undermines the expectation that disabling the installer in configuration prevents plugin installation.

What is the safest general fix pattern for this type of bug?

Apply server-side authorization enforcement for every privileged operation, making sure configuration flags like PLUGIN_INSTALLER are checked by the backend controller or service layer, not just used to toggle UI elements.
