Short explanation

Prior to version 1.6.0, SparkyFitness contains a server-side request forgery vulnerability because it does not validate destinations supplied in custom AI service settings [S0]. An authenticated user can save a custom AI service URL and trigger an affected AI flow to probe internal services [S0]. This issue is fixed in version 1.6.0 according to S0 [S0].

Why does it matter?

This vulnerability allows authenticated users to probe internal network services and send server-side POST requests [S0]. Successful exploitation can also lead to the disclosure of the AI system prompt [S0].

What should be done?

Upgrade the software to version 1.6.0 or later [S0].
Follow the official vendor security advisory [S0].
