A missing authorization vulnerability in the Maybe product allows authenticated users with low privileges to exploit global hosting settings. By leveraging unprotected actions in the Settings::HostingsController, these users can modify critical configurations, access the operator's Synth API key in plaintext, and manipulate registration settings. This poses a significant threat as it enables unauthorized changes that could disrupt the entire system functionality.
