# CVE-2026-72764

## Summary

- **CVE ID:** CVE-2026-72764
- **Severity:** MEDIUM
- **CVSS Score:** 5.8 (CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:N/VI:N/VA:N/SC:H/SI:H/SA:H)
- **CWE:** CWE-668
- **Published:** Aug 11, 2026
- **Last Modified:** Aug 11, 2026

## Description

n8n's JavaScript task runner shared a single module cache across all users' Code-node executions. In affected versions (before 1.123.67, 2.31.5, and 2.32.1), a user able to run a Code node could poison a cached module and thereby alter other users' Code-node executions on the same runner, affecting their confidentiality, integrity, or availability. This is a cross-user isolation break within a single n8n instance and does not constitute a sandbox escape or remote code execution. Only multi-user instances running the JS task runner with built-in or external modules enabled are affected.
