CVE-2026-0689
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.
Does this matter?
Lower severity and a low EPSS score (0.29%). Track it; it rarely justifies an emergency change on its own.
Description
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.
