CVE-2025-8450Network attack vector

Unauthenticated file upload via order forms

Published Aug 19, 2025 · Updated Aug 29, 2025

Unrestricted file upload in Fortra FileCatalyst Workflow 5.1.6 through 5.2.0 Build 80 allows remote attackers to upload arbitrary files. The order forms page accepts file submissions without authenticating the requester or restricting dangerous file types. A network-reachable order form is sufficient; uploaded content can modify stored data and interrupt service, while no direct disclosure is reported.
