CVE-2026-77084: n8n before 1.123.69 Remote Code Execution via Git Node Configuration Values

• Severity: high (CVSS 8.8 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.7% probability of exploitation in the next 30 days
• Public exploit or detection template: none known
• Published: 2026-08-20 · updated 2026-09-01
• Weakness: CWE-78

Description

n8n before 1.123.69 (and 2.x before 2.33.4 / 2.34.1) contains a code execution vulnerability in the Git node. The Git node executed certain repository-local git configuration values without neutralizing them, so any subsequent Git node operation against a repository containing a malicious value would execute it as the n8n process user. This is not reachable through the Git node's own configuration controls and requires a separate file-write vulnerability elsewhere to plant the malicious value.

Affected products

• n8n-io n8n: before 1.123.69; from 2.0.0 before 2.33.4; 2.34.0 — fixed in 1.123.69, 2.33.4

How to fix

Upgrade to a fixed version: n8n-io n8n 1.123.69, 2.33.4. Check the vendor advisory for mitigations.
