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.
