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

Quick assessment

Affected
n8n-io n8n
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

在 n8n 1.123.85 之前、2.x 系列 2.43.5 之前，以及 2.44.x 系列 2.44.1 之前的版本中，由于失败的轮询请求会存储原始请求头，导致 SeaTable 触发器节点的 API 令牌被错误地保存在执行错误数据中。任何能够查看工作流执行记录但无法读取凭据的用户，均可恢复该令牌并访问关联的 SeaTable 数据库。

Source: CVE Program / CVE List V5
Vulnerability 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.
