CVE-2026-118647
n8n before 1.123.85, 2.43.5, and 2.44.1 SeaTable Trigger API Token Exposure via Execution Data
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.
