CVE-2026-72764

HighCVSS 8.8/10Last modified Oct 29, 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.
