CVE-2026-48128Public exploitNetwork attack vector

Internal service disclosure via unvalidated automation queryId

Published May 27, 2026 · Updated May 27, 2026

SSRF in Budibase before 3.39.0 allows remote authenticated users to read internal service data through automation execution. The executeQuery step forwards an input-controlled queryId and parameters to executeV2AsAutomation without checking the query or destination. Exploitation requires builder-level access, a REST datasource aimed at an internal endpoint, and unrestricted server egress; responses appear in automation output.
