Missing Authorization vulnerability in SiteGround SiteGround Security allows Exploiting Incorrectly Configured Access Control Security Levels.This issue affects SiteGround Security: from n/a through 1.5.0.

The SiteGround Security WordPress plugin before 1.3.1 does not properly sanitize user input before using it in an SQL query, leading to an authenticated SQL injection issue.

The SiteGround Security plugin for WordPress is vulnerable to authentication bypass that allows unauthenticated users to log in as administrative users due to missing identity verification on the 2FA back-up code implementation that logs users in upon success. This affects versions up to, and including, 1.2.5.
