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. In versions prior to 3.0.8, WriteFileTool and ReadFileTool in Flowise do not restrict file path access, allowing authenticated attackers to exploit this vulnerability to read and write arbitrary files to any path in the file system, potentially leading to remote command execution. Flowise 3.0.8 fixes this vulnerability.

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 versions before 3.0.8 contain path traversal vulnerabilities in WriteFileTool and ReadFileTool that lack proper file path restrictions. Authenticated attackers can read and write files to arbitrary filesystem paths, enabling potential remote command execution.

MitigationUpgrade Flowise to version 3.0.8 or later. Additionally, audit logs for signs of exploitation, reset credentials for compromised accounts, and review file system permissions to limit the impact of any future path traversal attempts.

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 Flowise installation and version
    Locate the Flowise installation directory and check the version.json or package.json file, or run 'npm list flowise' or 'flowise --version' if CLI is available
    Affected if The installed version is any version before 3.0.8
  2. Determine if WriteFileTool is exposed
    Review the Flowise chatflows or API configurations for any deployed flows that include the WriteFileTool component. Check the components list in the Flowise UI or configuration files under the flows or storage directories
    Affected if WriteFileTool is enabled and accessible to authenticated users in any deployed flow
  3. Determine if ReadFileTool is exposed
    Review the Flowise chatflows or API configurations for any deployed flows that include the ReadFileTool component. Check the components list in the Flowise UI or configuration files under the flows or storage directories
    Affected if ReadFileTool is enabled and accessible to authenticated users in any deployed flow
  4. Check for file path restriction configuration
    Inspect the Flowise configuration file (typically flowise.json or .env) for any settings related to file access restrictions, allowed paths, or sandboxing for the file tools
    Affected if No file path allowlist or restriction is configured for WriteFileTool and ReadFileTool

You are affected if Flowise version is below 3.0.8 AND either WriteFileTool or ReadFileTool is deployed in an accessible flow without file path restrictions configured.

Interim mitigation

Upgrade Flowise to version 3.0.8 or later. Additionally, audit logs for signs of exploitation, reset credentials for compromised accounts, and review file system permissions to limit the impact of any future path traversal attempts.

Recommended fix High confidence

Flowise 3.0.8

  1. Backup your Flowise data and configuration files before upgrading
  2. Stop the Flowise service to prevent data corruption during upgrade
  3. Upgrade Flowise to version 3.0.8 by pulling the latest Docker image or using your installation method (e.g., `docker pull flowiseai/flowise:latest` or package manager update)
  4. Verify the upgrade completed successfully by checking the version number in the Flowise UI or CLI
  5. Restart the Flowise service
  6. Confirm that WriteFileTool and ReadFileTool now properly restrict file path access
