Vulnerability Description
TypeBot is a chatbot builder tool. Prior to 3.18.0, any authenticated non-guest workspace member can remove another workspace's public custom domain and make typebots on that domain unavailable. The custom-domain delete handler in handleDeleteCustomDomain.ts authorizes a caller against a client-supplied workspaceId but sends the client-supplied domain name to the shared Vercel project before verifying that the domain belongs to that workspace. This issue is fixed in version 3.18.0.
