Summary
Flowise before 3.1.2 contains an information disclosure vulnerability in the /api/v1/chatflows/apikey/:apikey endpoint. When the keyonly query parameter is omitted, the endpoint returns not only the chatflows bound to the supplied API key but also all chatflows across every workspace that have no API key assigned.
Risk Assessment
An attacker with a valid API key for one workspace can therefore retrieve the full ChatFlow configuration (including flowData, chatbotConfig, apiConfig, and credential IDs) of unprotected chatflows belonging to other workspaces, posing a serious data security risk.
Recommendation
It is recommended to update Flowise to version 3.1.2 or later to patch this vulnerability. Additionally, implementing appropriate filters in API queries to restrict data access to assigned workspaces is advisable.
Original NVD description (English source)
Flowise before 3.1.2 contains an information disclosure vulnerability in the /api/v1/chatflows/apikey/:apikey endpoint. When the keyonly query parameter is omitted (the default), the endpoint returns not only the chatflows bound to the supplied API key but also all chatflows across every workspace that have no API key assigned, because the underlying query lacks any workspace filter. An attacker with a valid API key for one workspace can therefore retrieve the full ChatFlow configuration (including flowData with system prompts and node configurations, chatbotConfig, apiConfig, and credential IDs) of unprotected chatflows belonging to other workspaces.
