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.
