CVE-2026-42100Public exploitNetwork attack vector

Authenticated service crash via malformed SQL query

Published May 19, 2026 · Updated May 19, 2026

Improper SQL-query handling in Sparx Systems Pro Cloud Server 6.1 and earlier allows remote authenticated users to crash the service. The exact parser locus is undisclosed; Pro Cloud Server terminates instead of safely rejecting a syntactically invalid crafted SQL query. Low-privileged network access is sufficient, and the reported consequence is interruption of the Pro Cloud Server service without confidentiality or integrity impact.
