# CVE-2026-118644: n8n before 2.41.5 and 2.42.2 Credential Theft via Error-Workflow Context Inheritance

Status: published. Published: 2026-10-28. Updated: 2026-11-03.

n8n before 2.41.5 and 2.42.x before 2.42.2 passes a failed workflow's full execution context, including the identity of the user who started the run, to the configured error workflow. A project editor can set a colleague's workflow settings.errorWorkflow to an error workflow they own, inherit the colleague's identity when that workflow fails, and resolve the colleague's per-user dynamic credential secrets.
