CVE-2026-0689 PUBLISHED

XIQ‑SE NAC Admin Credential Exposure via HTTP Response

Assigner: ExtremeNetworks
Reserved: 07.01.2026 Published: 02.03.2026 Updated: 02.03.2026

In ExtremeCloud IQ – Site Engine (XIQ‑SE) before 26.2.10, a vulnerability in the NAC administration interface allows an authenticated NAC administrator to retrieve masked sensitive parameters from HTTP responses. Although credentials appear redacted in the user interface, the application returns the underlying credential values in the HTTP response, enabling an authorized administrator to recover stored secrets that may exceed their intended access.

We would like to thank the Lockheed Martin Red Team for responsibly reporting this issue and working with us through coordinated disclosure.
