Routine

MEDIUM 6.5UPGRADE

CVE-2026-72763 is a medium-severity flaw (CVSS 6.5) affecting n8n. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

n8n before 1.123.67, 2.31.5, and 2.32.1 validates credential-access only for a node's top-level credentials and not for credentials referenced inside an Execute Sub-workflow node's inline workflow JSON. A member with Editor access to a shared workflow (when workflow sharing is enabled) who knows a target credential's ID can reference that credential in the inline JSON; it passes save-time and runtime validation and resolves in the parent workflow

Why this priority

No elevated risk signals yet

A fixed release or distro patch exists.

Affected: < 1.123.67 · >= 2.31.0 and < 2.31.5 · 2.32.0

Fixed in: 1.123.67, 2.31.5

Safe to downgrade to: a release before 2.31.0

1. Check installed version

npm ls n8n

2. UPGRADE to 1.123.67

npm install n8n@">=1.123.67"

3. If no update is available yet, DOWNGRADE to a release before 2.31.0

npm view n8n versions npm install n8n@"<2.31.0"

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.
