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.

n8n 在 1.123.85 之前、2.x 系列在 2.43.5 之前，以及 2.44.x 系列在 2.44.1 之前，其 Quick Base 节点存在过滤注入漏洞。该漏洞会将 Where 过滤条件以原始查询文本形式发送至 Quick Base API。攻击者若提供不可信输入（例如用于构建过滤条件的 Webhook 数据），可导致 Get Many 操作返回所有记录，或使 Delete 操作删除所有记录，且操作权限取决于工作流所使用的凭据。
