CVE-2026-45548Public exploitNetwork attack vector

Authenticated internal-service reads via unvalidated file URL

Published May 27, 2026 · Updated May 27, 2026

SSRF in Budibase before 3.34.8 allows remote authenticated users to read responses from internal services through the AI Extract File step. The processUrlFile function in packages/server/src/automations/steps/ai/extract.ts passes a supplied fileUrl directly to fetch instead of fetchWithBlacklist. Builder permissions and an AI Extract File automation using URL input are required; the server can expose cloud metadata, internal APIs, or network-service responses.
