CVE-2026-110841: n8n authorization bypass in agent chat resume endpoint

CVE-2026-110841 · Severity: info · Published 2026-10-14

n8n is an automation and integration platform where authenticated users can build agent workflows with tool approvals. A vulnerability allows project members to view other members' private agent conversations and approve their pending tool requests, causing tools to execute with results injected into another user's chat. This enables unauthorized access to sensitive conversations and manipulation of tool execution within shared projects.

Technologies: N8n. Vendors: N8n.

How to fix

Fixed in: 2.41.4, 2.42.0

Restrict n8n instance access to fully trusted users. Disable the Agents module by removing it from N8N_ENABLED_MODULES. Limit team project membership to the minimum required. Avoid using tools with "Require approval" enabled on agents accessible to multiple project members.

Technical details

The agent chat resume endpoint fails to validate that a suspended checkpoint belongs to the authenticated caller, accepting any run identifier from the request body. Combined with project-scoped read endpoints that lack per-user restrictions, an authenticated project member can enumerate and read arbitrary project members' agent conversations, then hijack pending tool approvals. Exploitation requires prior authentication and project membership, and results in confidentiality breach and unauthorized tool execution.

Affected products

n8n n8n before 2.41.4 and 2.42.0
