Summary
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.
