SCA: security update for flowise, flowise-components (GHSA-9gvv-qjj3-2p6g)

critical Tenable Cloud Security Plugin ID 473691

Description

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

- Flowise (packages flowise and flowise-components) in versions <= 3.1.2 contain a sandbox escape in the
vm2/@flowiseai/nodevm JavaScript sandbox. An authenticated user with access to the /api/v1/node-custom-
function endpoint can escape the sandbox by supplying attacker-controlled executablePath and args
parameters to puppeteer.launch(), which internally invokes child_process.spawn() outside the sandbox
boundary. This allows execution of arbitrary OS commands as the Flowise process user (root in the official
Docker image) and arbitrary host file disclosure via Chromium's file:// URL handling. In versions
3.0.8–3.1.2 exploitation requires ALLOW_BUILTIN_DEP=true; earlier versions are exploitable by default.
Fixed in 3.1.3. (CVE-2026-73483)

Solution

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