Vulnerability Title
dataCycle Public DataLink Text File Download Ignores Validity And Authorization
Source: CVE Program / CVE List V5
Vulnerability Description
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.
