This includes reviewing their current version, assessing exposure, and applying vendor remediation as available.

Technical summary

In dataCycle-CORE, the module handling core processing and framework rules, before and including version 25.07.3, a Standard user can enumerate other users' names and email addresses through `/users/search`, even though direct access to those user profiles is denied. This leaks internal staff addresses, full names, and existence of guest and external test accounts. The vulnerability has a CVSS score of 4.3 and a CVSS vector of CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N. Users should verify their version of dataCycle-CORE and apply the vendor's remediation as available.

Defensive priority

Apply vendor remediation as available to prevent user enumeration. Restrict access to the `/users/search` endpoint and monitor for suspicious activity related to user enumeration.

Recommended defensive actions

Apply the vendor's official remediation for this vulnerability
Restrict access to the `/users/search` endpoint
Monitor for suspicious activity related to user enumeration
Inventory and verify the version of dataCycle-CORE in use
