CVE-2022-4533: Limit Login Attempts Plus <= 1.1.0 - IP Address Spoofing to Protection Mechanism Bypass

The Limit Login Attempts Plus plugin for WordPress is vulnerable to IP Address Spoofing in versions up to, and including, 1.1.0. This is due to insufficient restrictions on where the IP Address information is being retrieved for request logging and login restrictions. Attackers can supply the X-Forwarded-For header with with a different IP Address that will be logged and can be used to bypass settings that may have blocked out an IP address or country from logging in.

Security readout for executives and security teams

Plain-English summary

This WordPress plugin can be tricked into trusting a user-supplied IP address header. An attacker may bypass IP or country-based login blocks, weakening brute-force protection. The issue is medium severity and not listed as known exploited in the supplied sources.

Executive priority

Treat this as a targeted WordPress hardening issue, not an emergency breach indicator. Prioritize externally exposed sites where this plugin is a primary login protection control.

Technical view

Limit Login Attempts Plus through version 1.1.0 retrieves IP address data too broadly for request logging and login restrictions. Supplying an X-Forwarded-For header can cause a different IP to be logged and used for access decisions, bypassing protections intended to block an IP address or country.

Likely exposure

Exposure is limited to WordPress sites running Limit Login Attempts Plus version 1.1.0 or earlier, especially where login restrictions depend on recorded client IP or country blocking.

Exploitation context

The supplied sources describe network-reachable, unauthenticated misuse with low attack complexity. They do not cite active exploitation, and the CVE is not marked in KEV.

Researcher notes

The affected behavior maps to CWE-348 and CVSS 5.3: AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N. Sources identify versions up to and including 1.1.0 but do not provide a fixed version in the supplied bundle.

Mitigation direction

  • Inventory WordPress sites for Limit Login Attempts Plus version 1.1.0 or earlier.
  • Check vendor, Wordfence, and WordPress plugin guidance for confirmed remediation.
  • Disable or replace the plugin if vulnerable and no fixed version is available.
  • Use trusted edge controls for login rate limiting where feasible.

Validation and detection

  • Confirm installed plugin name and version on each WordPress site.
  • Review whether login blocking depends on X-Forwarded-For-derived client IPs.
  • Check authentication logs for suspicious or inconsistent forwarded IP values.
  • Verify IP and country blocks cannot be bypassed in a controlled test environment.
