CVE-2026-32821
API Collection Impersonation Via user_email And Missing Object- Level 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, any authenticated API user who has their own access token can ask the collection API to evaluate permissions as a different user by supplying user_email. If the target user has collections, this can expose those collections through the API. In V4, once a collection id is known, the same controller also offers add_item and remove_item routes without any object-level authorize! checks,
creating a likely cross-user modification path. This is patched in version 26.06.08.
