State: Published
Severity: 5.3 Medium
Published: Oct 28, 2026
Updated: Oct 28, 2026
Reserved: Oct 28, 2026

Description

n8n before 1.123.85, 2.x before 2.43.5, and 2.44.x before 2.44.1 saves the SeaTable Trigger node's API token in error execution data, because failed poll requests store raw request headers. Users who can view workflow executions but cannot read the credential can recover the token and access the connected SeaTable base.
