Description
Maybe through 0.6.0 contains a missing authorization vulnerability that allows authenticated low-privilege member-role users to access and modify global hosting settings by exploiting unprotected show and update actions in the Settings::HostingsController, where the before_action ensure_admin filter is applied only to the clear_cache action. Attackers can read the operator's Synth API key rendered in plaintext via a form field value attribute, overwrite it with an attacker-controlled value, toggle public registration settings, and disable email confirmation requirements to disrupt the entire instance.
