TypeBot is a chatbot builder tool. Versions prior to 3.17.0 allow a low-privilege guest member of a workspace to exfiltrate stored OpenAI-compatible API keys by invoking the OpenAI model-listing helper with an attacker-controlled baseUrl. The vulnerable path decrypts the selected workspace credential, creates an OpenAI client with the secret in both apiKey and the explicit api-key header, and then sends the outbound request to the caller-supplied URL. Because the permission check accepts any readable workspace member and listCredentials reveals credential identifiers to guests, a guest can force the server to deliver the workspace secret to attacker infrastructure. Version 3.17.0 patches the issue.
