# CVE-2026-1470: n8n Unsafe Workflow Expression Evaluation Allows Remote Code Execution

**Signal:** High exploit likelihood. EPSS ranks it in the top 5% of all CVEs for likely exploitation in the next 30 days. (Computed from CISA KEV, EPSS and CVSS; not an editorial verdict.)

## Should you act?

- Not in CISA KEV , but CISA’s SSVC assessment records a public proof-of-concept, so attack code exists.
- EPSS 20.7% , percentile 98: FIRST’s model estimates a 20.7% chance of exploitation activity in the next 30 days, higher than 98% of all scored CVEs (very high). EPSS is a probability, not a verdict.
- Needs an account (low (any account)). Exposure depends on who can log in.
- Only applies if your dependency tree includes n8n (npm) < 1.123.17, fixed in 1.123.17 ; n8n (npm) >= 2.0.0, < 2.4.5, fixed in 2.4.5 ; n8n (npm) >= 2.5.0, < 2.5.1, fixed in 2.5.1 . Check your lockfile, including transitive dependencies.

## What it is

n8n contains a critical Remote Code Execution (RCE) vulnerability in its workflow Expression evaluation system. Expressions supplied by authenticated users during workflow configuration may be evaluated in an execution context that is not sufficiently isolated from the underlying runtime. An authenticated attacker could abuse this behavior to execute arbitrary code with the privileges of the n8n process. Successful exploitation may lead to full compromise of the affected instance, including unauthorized access to sensitive data, modification of workflows, and execution of system-level operations.

## Affected packages

- npm `n8n` < 1.123.17 → fixed: 1.123.17
- npm `n8n` >= 2.0.0, < 2.4.5 → fixed: 2.4.5
- npm `n8n` >= 2.5.0, < 2.5.1 → fixed: 2.5.1

## Affected products (CVE record)

-  n8n: < 1.123.17, 2.0.0 < 2.4.5, 2.5.0 < 2.5.1

## Severity

- JFROG CVSS 3.1: 9.9 `CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H`
- GitHub CVSS 3.1: 9.9 `CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H`

## Exploitation

- CISA KEV: not listed (no confirmed in-the-wild exploitation known to CISA).
- CISA SSVC assessment: exploitation poc , automatable no , technical impact total .
- FIRST EPSS (model of 2026-10-21): 20.68% probability of exploitation activity in the next 30 days; percentile 98.
