CVE-2026-43685Network attack vector

Authenticated OS command execution via unsanitized ODBC test

Published May 12, 2026 · Updated May 12, 2026

OS command injection in Claris FileMaker Cloud before 2.22.0.5 allows remote authenticated users to execute commands through an ODBC test. The External ODBC Data Source connection test uses unsanitized administrator-supplied input when invoking operating system commands. Admin Console privileges are required, and successful exploitation executes arbitrary commands on the underlying FileMaker Cloud host.
