CVE-2026-19357Public exploitNetwork attack vector

Unauthenticated information disclosure via ms-mdiy form endpoint

Published Aug 9, 2026 · Updated Aug 9, 2026

Information disclosure in MingSoft MCMS 3.0.0 through 3.0.6 allows remote attackers to read unspecified data via /mdiy/form/get. The public record identifies the ms-mdiy handler for that route but does not disclose the request manipulation, affected data, or erroneous operation that causes the response. The route is network-accessible without privileges or user interaction, and the documented consequence is limited to confidentiality loss.
