Miggo AIRoot Cause Analysis

The vulnerability stems from the fact that ModelStorage classes (including relation models for Many2Many fields) had RPC methods enabled by default in their init method, without requiring the class to inherit from ModelView. The patch explicitly gates RPC method availability on the presence of ModelView inheritance. This means the root cause was the unconditional assignment of RPC permissions in ModelStorage.init, which directly exposed the create/write/delete/copy RPC methods on unintended models.
