A high-severity security flaw in dataCycle-CORE from datacycle-engine. There are no confirmed reports of exploitation so far. The chance it is exploited in the next 30 days is estimated at 0.4% (higher than 34% of all known vulnerabilities).
Official 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.
