Detailed vulnerability description
The vulnerability allows a remote user to disclose sensitive information across workspace boundaries.
The vulnerability exists due to improper access control in the /api/v1/chatflows/apikey/:apikey endpoint when handling requests without the keyonly query parameter. A remote user can send a request with a valid API key to disclose sensitive information across workspace boundaries.
The response can include full chatflow objects for unprotected chatflows from other workspaces, including flowData, chatbotConfig, apiConfig, text-to-speech and speech-to-text configuration, analytics configuration, and credential IDs.
