HIGH 8.8UPGRADE

CVE-2026-77084 is a high-severity flaw (CVSS 8.8) affecting n8n. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

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 vulne

n8n n8n UPGRADE

Affected: < 1.123.69 · >= 2.0.0 and < 2.33.4 · 2.34.0

Fixed in: 1.123.69, 2.33.4

Safe to downgrade to: a release before 2.0.0

1. Check installed version

npm ls n8n

2. UPGRADE to 1.123.69

npm install n8n@">=1.123.69"

3. If no update is available yet, DOWNGRADE to a release before 2.0.0

npm view n8n versions npm install n8n@"<2.0.0"

Downgrade risk

Downgrading can break dependent software and may reopen older bugs. Read the distro advisory first and test on a non-production host.

After downgrade

Restart the service, and keep the package held until a fixed release ships.
