According to its banner, the version of Flowise running on the remote host is < 3.1.2. It is, therefore, affected by multiple vulnerabilities :

- An hardcoded CORS wildcard on TTS endpoint enables abuse from any webpage

- An RCE through Flowise MCP

- A Mass Assignment in Chatflow Update Endpoint

- A Mass Assignment in Tool Update Endpoint

- A Mass Assignment in Assistant Update Endpoint

- A Mass Assignment in Variable Update Endpoint

- A Mass Assignment in PUT /api/v1/user

- An Authenticated Host RCE via POST /api/v1/node-custom-function

- A Cross-Workspace Chatflow Disclosure via chatflows/apikey Endpoint

- A Credential Data Leak

- Vector Store No Permission Checks

- CustomTemplate create+update mass-assignment

- Assistant create+update mass-assignment allows cross-workspace assistant takeover

- DatasetRow create+update mass-assignment

- Dataset create+update mass-assignment

- Evaluation create+update mass-assignment

Note that the scanner has not tested for these issues but has instead relied only on the application's self-reported version number.

There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - Flowise is a drag & drop user interface to build a customized large language model flow. Prior to version
    3.1.2, POST /api/v1/node-custom-function lacks route-level authorization, allowing any authenticated user
    or API key to submit arbitrary JavaScript to the Custom JS Function node. When E2B_APIKEY is not
    configured — the common deployment case — Flowise executes this code inside a NodeVM sandbox. This sandbox
    can be escaped, allowing an attacker to reach the host process object and execute system commands via
    child_process. The result is authenticated remote code execution on the Flowise server host. This issue
    has been patched in version 3.1.2. (CVE-2026-46442)
