CVE-2026-45548 is a high-severity vulnerability rated 7.7/10 on the CVSS scale. 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. EPSS estimates a 0.26% chance of exploitation in the next 30 days.
