Published: May 27, 2026Updated: May 27, 2026 Sources: CVE List NVD
NVD MITRE
7.7CVSS
HIGH

Budibase is an open-source low-code platform. Prior to 3.34.8, the processUrlFile function in packages/server/src/automations/steps/ai/extract.ts uses fetch(fileUrl) directly without the IP blacklist validation that is consistently applied to all other automation steps. This allows an authenticated user to trigger server-side requests to internal network addresses. This vulnerability is fixed in 3.34.8.
