What is CVE-2026-32807?
CVE-2026-32807 is a high-severity missing authorization vulnerability in datacycle-engine dataCycle-CORE, published on 20 Jul 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.
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.
Weakness: CWE-285
