Budibase is an open-source low-code platform. Prior to 3.41.3, automation steps in packages/server/src/automations/steps/outgoingWebhook.ts, packages/server/src/automations/steps/zapier.ts, packages/server/src/automations/steps/n8n.ts, packages/server/src/automations/steps/slack.ts, and packages/server/src/automations/steps/discord.ts use node-fetch on user-provided URLs without the BLACKLIST_IPS enforcement used by the REST integration, allowing an authenticated user to make server-side requests to cloud metadata and internal services. This issue is fixed in version 3.41.3.
