Title
TypeBot vulnerable to cross-workspace OAuth credential takeover in updateOAuthCredentials via missing object binding
Summary
TypeBot is a chatbot builder tool. Versions prior to 3.17.0 allow a low-privilege read collaborator to extract a workspace OAuth `credentialsId` from a readable bot configuration and then overwrite that credential through `handleUpdateOAuthCredentials()` by supplying an attacker-controlled writable `workspaceId`. The update path validates only the attacker-supplied workspace and then updates the credential record by global `id` alone, while also rewriting the credential's `workspaceId`. This allows cross-workspace OAuth credential takeover and reassignment. Version 3.17.0 patches the issue.
