AffiliateWP SQL Injection Vulnerability in WordPress Plugin

A SQL injection vulnerability has been identified in the AffiliateWP plugin for WordPress, affecting all versions through 2.28.2. The issue arises in the ajax_get_affiliate_id_from_login function, where insufficient escaping of user-supplied parameters and inadequate preparation of the SQL query allow unauthenticated attackers to inject additional SQL commands. This exploitation could lead to the extraction of sensitive information from the database.

Impact

Exploitation of this vulnerability allows for SQL injection, where attackers can manipulate SQL queries to access or modify database information. In this case, it could be used to extract sensitive data from the database.

Remediation

Users are advised to update the AffiliateWP plugin to version 2.29.0 or a newer patched version.
