# WordPress OTP Login plugin lets attackers brute-force one-time codes and take over accounts

The OTP Login & Register WooCommerce plugin before 2.7.3 tracks its OTP attempt limit against a value the client controls, so the limit can be reset freely. An unauthenticated attacker can brute-force the short numeric login code and sign in to an account without knowing its password.

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

## How to check

- Check the installed version of the OTP Login & Register Woocommerce plugin in the WordPress admin plugin list, or run `wp plugin get <plugin-slug> --field=version` with WP-CLI
- Confirm whether the plugin is active on the site

## Fix

- Update the OTP Login & Register Woocommerce plugin to `2.7.3` or later
- If an update is not possible, deactivate the plugin until it is patched

## Timeline

## From the sources

The OTP Login & Register Woocommerce WordPress plugin before 2.7.3 does not adequately limit one-time-password verification attempts, because the attempt limit is tracked against a value the client itself supplies and can change freely, allowing an unauthenticated attacker to bypass the limit and brute-force the short numeric login code to take over an account without its password.
