Preliminary research

Ask the Agent Nicely: Two Authorization Bypasses in n8n AI Agents

Antonio De Turris · Antonio De Turris · 14 September 2026

AI-collected research leads through 1 October 2026, including a bounded September review of selected social and community sources. Unranked, incomplete, not community-vetted, and subject to change.

Two n8n agent paths omitted authorization enforced elsewhere. A read-only Project Viewer could execute tool nodes with project credentials, while the MCP client sent a shared credential to an arbitrary server without applying its allowed-domain restriction.
