# Zenitel Connect: failed logins lock out user accounts from the web interface

Link for people: https://infrastack.ai/live/CVE-2026-105624 (this .md is for agents)

Zenitel Connect before 1.11.0 locks a user account after repeated failed logins. A remote attacker who knows or guesses a username can keep triggering that lockout and deny the real user web access.

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

## How to check

- Check the installed Zenitel Connect version in the web interface or product documentation; `unknown` if the sources do not give the exact location.
- Look for any version below `1.11.0`.

## Fix

- Zenitel Connect: `1.11.0` (the sources say versions before 1.11.0 are affected).

## Timeline

- 2026-11-13T16:47:32+00:00 nvd https://nvd.nist.gov/vuln/detail/CVE-2026-105624

## From the sources

The login flow in Zenitel Connect before 1.11.0 applies per-account lockout on repeated failed login attempts, which allows remote attackers to cause a denial of service (temporary lockout of targeted user accounts from the web interface, repeatable for as long as the attack continues) via repeated failed login requests for a known or guessed username. Intercom call handling is not affected.
