• CVE-2025-57760: 0.54% estimated exploitation activity in the next 30 days; percentile 45.40 (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.

This vulnerability was discovered by researchers at Check Point. We are sharing this report as part of a responsible disclosure process and are happy to assist in validation and remediation if needed. Summary A privilege escalation vulnerability exists in Langflow containers where an authenticated user with RCE access can invoke the internal CLI command langflow superuser to create a new administrative user. This results in full superuser access, even if the user initially registered through the UI as a regular (non-admin) account. Details Langflow's Docker image includes a CLI binary at /app/.venv/bin/langflow that exposes sensitive commands, including: langflow superuser This command allows creation of a new superuser without checking whether one already exists. When combined with code execution (e.g., via the authenticated /api/v1/validate/code endpoint), a low-privileged user can execute: /app/.venv/bin/langflow superuser inside the container, and elevate themselves to full…

# Patch Next advisory brief: CVE-2025-57760

Advisory: Langflow Vulnerable to Privilege Escalation via CLI Superuser Creation (Post-RCE)
IDs: CVE-2025-57760, GHSA-4gv9-mp8m-592r
Record: https://patchnext.com/advisories/cve-2025-57760 (revision 2, source checked 26 Oct 2026, 13:36 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 8.8)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: langflow-base 0.5.1; langflow 1.5.1. A vendor fix does not mean a deployment is fixed.

## Affected components
- PyPI langflow-base: affected <= 0.5.0; fixed in 0.5.1
- PyPI langflow: affected <= 1.5.0; fixed in 1.5.1

## Suggested inspection (read-only)
- `python -m pip show langflow-base`: prints the installed version. Run with the environment that serves production active.
- `python -m pip show langflow`: prints the installed version. Run with the environment that serves production active.

## 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 langflow-base, langflow.
- 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.
