Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Flowise is a drag & drop user interface to build a customized large language model flow. Prior to version 3.1.2, evaluator create and update mass-assignment allows cross-workspace evaluator takeover. This issue has been patched in version 3.1.2.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

Flowise prior to version 3.1.2 contains a mass-assignment vulnerability in the evaluator create and update endpoints that allows attackers to modify evaluator attributes they should not have access to, enabling cross-workspace evaluator takeover due to improper authorization controls.

MitigationUpgrade to Flowise version 3.1.2 or later, which patches the mass-assignment vulnerability and implements proper workspace isolation for evaluator operations.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify installed Flowise version
    Check the package.json file in the Flowise installation directory, or run 'npm list flowise' or check the Docker image tag if running containerized
    Affected if The installed version is prior to 3.1.2 (e.g., 3.1.1, 3.1.0, earlier releases)
  2. Determine if evaluator feature is in use
    Inspect the Flowise application for any created evaluators - look in the database or UI for documents or records labeled as evaluators
    Affected if Any evaluator records exist in the system, as the vulnerability affects create and update operations on this entity
  3. Verify multi-workspace configuration
    Check Flowise configuration settings or database for evidence of multiple workspace definitions - look for workspace-related tables or configuration keys
    Affected if More than one workspace is configured, as the flaw enables cross-workspace evaluator manipulation
  4. Inspect evaluator access patterns
    Query the evaluator records in the database and compare the workspace ID assigned to each evaluator against the workspace IDs of the users who created or modified them
    Affected if Any evaluator exists where the modifying user's assigned workspace differs from the evaluator's workspace, indicating potential unauthorized cross-workspace access

You are affected if Flowise version is below 3.1.2 AND the evaluator feature is enabled with multiple workspaces in use, as the vulnerability allows authenticated users to modify evaluators outside their assigned workspace.

Upgrade available Upgrade to 3.1.2 or later
Fixed in 3.1.2
Interim mitigation

Upgrade to Flowise version 3.1.2 or later, which patches the mass-assignment vulnerability and implements proper workspace isolation for evaluator operations.

Recommended fix High confidence

Flowise version 3.1.2

  1. 1. Backup your current Flowise installation and any associated data
  2. 2. Stop the Flowise service if it's currently running
  3. 3. If installed via npm, run: npm install -g [email protected]
  4. 4. If using Docker, update your image tag to the version 3.1.2 and recreate the container
  5. 5. After upgrading, verify the service starts successfully
  6. 6. Test evaluator creation and update functionality to confirm the mass-assignment vulnerability is resolved
  7. 7. Review evaluator objects to ensure no unauthorized cross-workspace access has occurred
