• CVE-2024-58351: 0.93% estimated exploitation activity in the next 30 days; percentile 60.52 (FIRST EPSS, 2026-11-03). This is a model estimate, not proof of exploitation or customer exposure.

As published by the source; long descriptions are shortened.

Impact Flowise allows developers to inject configuration into the Chainflow during execution through the overrideConfig option. This is supported in both the frontend web integration and the backend Prediction API. This has a range of fundamental issues that are a major security vulnerability. While this feature is intentional, it should have strong protections added and be disabled by default. These issues include: 1. Remote code execution. While inside a sandbox this allows for 1. Sandbox escape 2. DoS by crashing the server 3. SSRF 2. Prompt Injection, both System and User 1. Full control over LLM prompts 2. Server variable and data exfiltration And many many more such as altering the flow of a conversation, prompt exfiltration via LLM proxying etc. These issues are self-targeted and do not persist to other users but do leave the server and business exposed. All issues are shown with the API but also work with the web embed. Workarounds - overrideConfig should be disabled by…

# Patch Next advisory brief: CVE-2024-58351

Advisory: Flowise OverrideConfig security vulnerability
IDs: CVE-2024-58351, GHSA-5cph-wvm9-45gj
Record: https://patchnext.com/advisories/cve-2024-58351 (revision 3, source checked 26 Oct 2026, 13:02 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 8.6)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: flowise 2.1.4. A vendor fix does not mean a deployment is fixed.

## Affected components
- npm flowise: affected < 2.1.4; fixed in 2.1.4

## Suggested inspection (read-only)
- `npm ls flowise --all`: lists every installed copy and version, including transitive ones. Run in the project root after `npm ci`.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on flowise.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.
