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, a mass assignment vulnerability exists in the chatflow update endpoint of FlowiseAI. The endpoint
    allows clients to modify server-controlled properties such as deployed, isPublic, workspaceId,
    createdDate, and updatedDate when updating a chatflow object. Due to missing server-side validation and
    authorization checks, an authenticated user can manipulate internal attributes of a chatflow and reassign
    it to another workspace. This allows cross-workspace resource reassignment and unauthorized modification
    of deployment and visibility settings. This issue has been patched in version 3.1.2. (CVE-2026-42863)
