Summary

NocoBase is an AI-powered no-code/low-code platform for building business applications and enterprise solutions. Prior to version 2.0.37, NocoBase's workflow HTTP request plugin and custom request action plugin make server-side HTTP requests to user-provided URLs without any SSRF protection. An authenticated user can access internal network services, cloud metadata endpoints, and localhost. Version 2.0.37 contains a patch.
