# INFINITT ULite: login error page reflects script via crafted link

Link for people: https://infrastack.ai/live/CVE-2026-19876 (this .md is for agents)

INFINITT ULite's login and SSO error page echoes an unsanitized request parameter back without encoding. An attacker who gets a victim to open a crafted link can run arbitrary JavaScript in the victim's browser.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the installed ULite version against `5.0.2.1_BN48_20260528` and earlier; unknown otherwise
- Confirm whether the login or SSO error page is reachable from the internet or from users' browsers

## Fix

- INFINITT ULite: move to `5.0.2.1 BN50`

## Timeline

- 2026-11-06T09:40:32+00:00 nvd https://nvd.nist.gov/vuln/detail/CVE-2026-19876

## From the sources

A reflected cross-site scripting (XSS) vulnerability in the login/SSO error page of INFINITT ULite 5.0.2.1_BN48_20260528 and earlier allows an unauthenticated remote attacker to execute arbitrary JavaScript in the browser of a victim who opens a crafted link. An unsanitized request parameter is reflected without output encoding. Fixed in ULite 5.0.2.1 BN50.
