CVE-2026-72763
HighCVSS 7.2Exploitation Probability (EPSS)
Low risk12th percentile - higher than 12% of all known CVEs
Summary
Vulnerability in n8n before versions 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's project context, allowing the attacker to use or exfiltrate credentials they are not permitted to access.
Risk Assessment
The risk includes unauthorized access to credentials, potentially leading to data and resource security breaches.
Recommendation
Upgrade n8n to versions 1.123.67, 2.31.5, or 2.32.1 which contain the fix.
