SCA: security update for flowise, flowise-components (GHSA-wg86-r78f-74mp)

critical Tenable Self-Hosted Container Security Plugin ID 445639

Description

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

- Flowise is a drag-and-drop user interface for building customized large language model (LLM) flows. Prior
to version 3.1.3, several custom-tool components — AgentAsTool, ChatflowTool, and ExecuteFlow — ran code
in the in-process vm2 sandbox. To build that code, they inserted a user-controlled baseURL value straight
into the JavaScript source, for example const url = "${baseURL}/..."; . The only check on baseURL was
isValidURL , but a valid-looking URL can still contain characters that break out of a code string. An
authenticated user could craft a baseURL that passed this check, closed the surrounding string, and
injected their own JavaScript into the sandboxed script (code injection, CWE-94). The vm2 sandbox runs in
the same Node.js process as Flowise and exposes risky dependencies. As a result, the injected code could
escape the sandbox and run arbitrary code on the Flowise server as the Flowise process user. Exploitation
only requires an authenticated session. The issue is fixed in version 3.1.3, which passes the URL to the
sandbox as data instead of inserting it into code and adds stricter URL validation. (CVE-2026-69253)

Solution

Update the flowise library and its related packages to version 3.1.3 or later.
