A member with editor access to a shared workflow could reference a credential they were not permitted to use inside that inline JSON; it passed both save-time and runtime validation and resolved in the parent workflow's project context, letting the member use or exfiltrate a credential they could not otherwise access.\n\nExploitation requires workflow sharing to be enabled and the attacker to have been explicitly granted Editor access to a shared workflow. The attacker must also know the target credential's ID.\n\n## Patches\n\nThe issue has been fixed in n8n versions 1.123.67, 2.31.5, and 2.32.1. Users should upgrade to one of these versions or later to remediate the vulnerability.\n\n## Workarounds\n\nIf upgrading is not immediately possible, administrators should consider the following temporary mitigations:\n- Restrict workflow sharing to fully trusted users only, and avoid granting Editor access to untrusted members on workflows that use sensitive credentials.\n- Audit shared workflows for Execute Sub-workflow nodes with Source = \"Parameter\" and review their inline workflow definitions for unexpected credential references.\n- Restrict network egress from the n8n instance to prevent connections to attacker-controlled endpoints.\n\nThese workarounds do not fully remediate the risk and should only be used as short-term mitigation measures.\n\n## Affected packages\n\n- `n8n < 1.123.67`\n- `n8n >= 2.32.0, < 2.32.1`\n- `n8n >= 2.0.0-rc.0, < 2.31.5`\n\n## Remediation\n\nUpgrade to a patched release:\n\n- `n8n 1.123.67`\n- `n8n 2.32.1`\n- `n8n 2.31.5`","depth":"twilight","depthScore":41,"depthScoreParts":{"impact":41.3,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
