CVE-2026-77084: n8n

High severity, CVSS 8.8. EPSS: 0.7% chance of exploitation in the next 30 days.

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 n8n: before 1.123.69 (fixed in 1.123.69); from 2.0.0, before 2.33.4 (fixed in 2.33.4); version 2.34.0 only
