CVE-2026-54312
n8n: Microsoft SQL Node Prototype Pollution
Description
n8n is an open source workflow automation platform. Prior to 2.24.0, an authenticated user with permission to create or modify workflows could achieve global prototype pollution via the Microsoft SQL node by supplying a crafted value as the table parameter. This pollutes Object.prototype process-wide for the lifetime of the n8n server process, causing application-wide validation failures and rendering the n8n instance completely non-functional until restarted. This vulnerability is fixed in 2.24.0.
