How severe is CVE-2026-72765?

No CVSS score has been assigned to CVE-2026-72765 yet. Review the advisory details and affected package list to assess your exposure.

Which packages are affected by CVE-2026-72765?

CVE-2026-72765 affects the following packages: n8n (npm), n8n (npm). Ecosystems affected: npm.

How do I fix CVE-2026-72765?

Update n8n to 2.32.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2026-72765 is resolved across your whole dependency graph.

How do I detect CVE-2026-72765 in my npm dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for n8n, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate CVE-2026-72765 if there is no patch (or I can't update yet)?

Stop passing untrusted input into the interpreter or shell: call the affected binary with an argument array rather than a composed command string, reject anything outside a strict allowlist of expected values, and run the component under an account that cannot reach beyond the work it legitimately does.

Is CVE-2026-72765 actively exploited in the wild?

No public exploit code has been indexed for CVE-2026-72765 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

What is the EPSS score for CVE-2026-72765?

CVE-2026-72765 has an EPSS (Exploit Prediction Scoring System) score of 0.9%, placing it in the 57th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

What type of vulnerability is CVE-2026-72765?

CVE-2026-72765 is classified as Code Injection (CWE-94). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation. This is a high-impact weakness class that often enables remote code execution or data exposure.

When was CVE-2026-72765 published, and has it been updated?

CVE-2026-72765 was published on August 11, 2026 and was last updated on September 3, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Description

Impact

An authenticated user with permission to create or modify workflows could abuse crafted expressions using arrow functions to bypass the expression sandbox, triggering unintended system command execution on the host running n8n.

Patches

The issue has been fixed in n8n versions 2.31.5 and 2.32.1. Users should upgrade to one of these versions or later to remediate the vulnerability.

Workarounds

If upgrading is not immediately possible, administrators should consider the following temporary mitigations:

Restrict n8n instance access to fully trusted users only.
Restrict workflow creation and editing permissions to fully trusted users only.

These workarounds do not fully remediate the risk and should only be used as short-term mitigation measures.
