Is this vulnerability remotely exploitable over the internet?

Yes, if the Chikitsa instance is exposed over the network and an attacker can obtain valid credentials with access to the plugin upload feature, they can exploit this purely via HTTP(S) requests.

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

The attacker needs an authenticated account with permissions to use the module or plugin upload functionality. This is often an administrative or privileged user role but depends on how roles are configured in the specific deployment.

What is the safest general fix pattern for this vulnerability class?

The most robust pattern is to prevent user-controlled files from ever becoming executable by the server. This includes strictly validating upload contents, storing them outside of executable directories, and implementing a constrained, possibly signed, plugin format rather than accepting arbitrary archives.
