CVE-2026-32807 | dataCycle Public DataLink Text File Download Ignores Validity And Authorization

dataCycle is a data management system for centrally storing, managing, searching, finding, and distributing data. In dataCycle-CORE, the module handling core processing and framework rules, before and including version 25.07.3, anyone with a DataLink UUID can fetch the attached text file directly, even if the link is expired, the caller is unauthenticated, or the normal show flow would have denied access. Because the route is public and the mailer embeds the direct file URL, any leaked, forwarded, logged, or stale email link can continue to expose the attachment.
