CVE-2026-32821: CWE-285: Improper Authorization in datacycle-engine dataCycle-CORE
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.
AI Analysis
Technical Summary
The vulnerability in dataCycle-CORE (up to version 25.07.3) involves improper authorization (CWE-285) where authenticated API users can impersonate other users by supplying a user_email parameter to the collection API, exposing collections they should not access. Furthermore, in API version 4, the add_item and remove_item endpoints lack object-level authorization checks, enabling cross-user modification of collections. The issue is fixed in version 26.06.08. The CVSS 3.1 score is 8.1 (high), reflecting network attack vector, low attack complexity, requiring low privileges, no user interaction, unchanged scope, and high confidentiality and integrity impact.
Potential Impact
An authenticated user with their own access token can access and potentially modify collections belonging to other users without proper authorization. This leads to unauthorized disclosure of sensitive data (collections) and unauthorized modification of data, impacting confidentiality and integrity. Availability is not affected. The vulnerability could allow privilege escalation within the application context.
Mitigation Recommendations
A fix is available in dataCycle-CORE version 26.06.08. Users should upgrade to this version to remediate the improper authorization vulnerability. Until upgraded, restrict API access to trusted users only and monitor for suspicious activity related to collection access and modification. Patch status is confirmed by the vendor advisory indicating the issue is fixed in 26.06.08.
