# Defender Security WordPress plugin: two-factor login can be brute-forced

Link for people: https://infrastack.ai/live/CVE-2026-119040 (this .md is for agents)

The Defender Security WordPress plugin before 6.4.1 does not limit failed two-factor authentication attempts in its default configuration. An attacker who already knows a user's password can guess the one-time code until they get in.

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

## How to check

- Check the installed Defender Security version in the WordPress plugin list or with `wp plugin get wp-defender --field=version`
- Confirm whether two-factor login is enabled in the plugin's settings

## From the sources

The Defender Security  WordPress plugin before 6.4.1 does not limit the number of failed two-factor authentication attempts in its default configuration, allowing an attacker who already knows a victim's password to brute-force the one-time code and defeat the second authentication factor.
