Description

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.

Description quoted from the NVD record.

Who is affected

Flowise is a tool for building apps and chatbots that use AI language models. This flaw affects versions before 3.1.2. It sits in the part of Flowise that lists chat workflows (called chatflows) linked to an access key. By default, someone with a valid access key for one workspace can also see every chatflow in other workspaces that has no access key assigned. They could read the full setup of those chatflows, including the instructions given to the AI, other configuration details and references to stored login credentials. This flaw is rated High.

What to do

  1. If someone in your organization installed or runs Flowise, ask that person to check which version of Flowise is in use.
  2. Have them update Flowise to version 3.1.2 or later, which fixes this flaw. Any version before 3.1.2 is affected.
  3. If an IT provider or vendor runs Flowise for your organization, send them this advisory and ask when the update will be done.
  4. Give this update priority if your Flowise setup has more than one workspace, since the flaw lets anyone holding an access key for one workspace see chatflows from others.
