CVE-2026-48999Network attack vector

Session hijacking via stored script execution

Published May 27, 2026 · Updated May 27, 2026

Stored XSS in ZTE ZXUniPOS NDS-LTE before 24.40.40CP01, except 24.30.40CP03, allows remote authenticated users to run browser scripts. ZTE states that injected JavaScript is stored and automatically loaded when another user opens an affected page, but does not identify the input field, endpoint, or output-encoding failure. High-privileged access and victim interaction are required; exploitation exposes cookies and session privileges and permits page-content changes.
