What is CVE-2026-45548?

Budibase, an open-source low-code platform, contains a vulnerability in its automation feature prior to version 3.34.8. The issue resides in the processUrlFile function, where fetch(fileUrl) is invoked without the necessary IP blacklist validation. This allows malicious authenticated users to initiate server-side requests to internal network addresses, potentially exposing sensitive information or services. Users are advised to update to version 3.34.8 or later to mitigate this risk.
