TypeBot vulnerable to OpenAI API key exfiltration in listModels via attacker-controlled baseUrl

AI Analysis

No AI analysis yet.

Description

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.
