SCA: security update for flowise (GHSA-c2c9-mfw7-p8hw)

medium Tenable Self-Hosted Container Security Plugin ID 442241

Description

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

 - 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. (CVE-2026-56268)

Solution

Update the flowise library and its related packages to version 3.1.2 or later.
