FUXA Unauthenticated Remote Code Execution in Node-RED Integration
Exploitation Status
No confirmed exploitation observed yet
- CISA assesses this as automatable — exploitation doesn’t require manual, per-target effort, which raises the odds of mass scanning and opportunistic attacks.
- A successful exploit gives an attacker total control of the affected component, not partial access.
- CISA’s own triage has not observed active exploitation or public proof-of-concept code for this CVE as of its last assessment.

fuxa-servernpmDescription
Summary
Description An authentication bypass vulnerability in FUXA allows an unauthenticated, remote attacker to execute arbitrary code on the server when the Node-RED plugin is enabled. This affects FUXA version 1.2.8 through version 1.2.10. This has been patched in FUXA version 1.2.11.
Impact
This affects all deployments with the Node-RED plugin enabled, including those with runtime.settings.secureEnabled set to true.
Exploitation allows an unauthenticated, remote attacker to send a specially crafted request to the /nodered/flows endpoint to bypass authentication checks, granting the attacker administrative access to the Node-RED deployment API. By submitting a malicious flow configuration, an attacker can execute arbitrary code in the context of the FUXA service. Depending on deployment configuration and permissions, this may lead to full system compromise and could further expose connected ICS/SCADA environments to follow-on actions.
Patches
This issue has been patched in FUXA version 1.2.11. Users are strongly encouraged to update to the latest available release.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for fuxa-server, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update fuxa-server to 1.2.11 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-v4p5-w6r3-2x4f is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-v4p5-w6r3-2x4f can be triaged on real exposure rather than presence alone.
Tailored to GHSA-v4p5-w6r3-2x4f. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-v4p5-w6r3-2x4f in your dependencies?
O3 Security finds GHSA-v4p5-w6r3-2x4f across npm dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
