CVE-2026-43680Network attack vector

Admin-level code execution via schedule-type restriction bypass

Published May 12, 2026 · Updated May 12, 2026

Code injection in Claris FileMaker Cloud before 2.22.0.5 allows remote authenticated users with Admin Console privileges to execute OS commands. The schedule back end accepts OS Script schedule types that the front end blocks, allowing a privileged request to bypass the UI-only restriction. Admin Console privileges are required; successful exploitation runs arbitrary commands on the managed host and can compromise hosted data and service operation.
