Summaryinfo

A vulnerability described as critical has been identified in n8n-io n8n. Affected by this issue is some unknown functionality of the component JavaScript Task Runner.

Detailsinfo

A vulnerability, which was classified as critical, was found in n8n-io n8n. Affected is an unknown code block of the component JavaScript Task Runner. The manipulation with an unknown input leads to a privileges management vulnerability. CWE is classifying the issue as CWE-269. The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

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.

The advisory is shared for download at github.com. This vulnerability is traded as CVE-2026-72764 since 08/10/2026. The exploitability is told to be easy. It is possible to launch the attack remotely. There are neither technical details nor an exploit publicly available. The MITRE ATT&CK project declares the attack technique as T1068.

Upgrading to version 1.123.67, 2.31.5 or 2.32.1 eliminates this vulnerability.
