Who should care

Organizations using dataCycle-CORE, especially those with internal staff and external test accounts, should be aware of this vulnerability and take necessary actions to protect their systems. 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
  • Consider implementing compensating controls to detect and prevent user enumeration attacks
  • Review compensating controls for exposed systems while remediation is scheduled and verified
  • Track exceptions, retest remediated assets, and close the item only after evidence is documented
