Effective Prevention Methods for SQL-injection

SQL injection in WordPress plugins is a vulnerability in which an attacker can inject and execute malicious SQL code in the site database. This usually happens if user input (such as form data or URL parameters) is not sufficiently checked or filtered before being used in SQL queries.

Effective Prevention Methods for XSS

Cross-site scripting (XSS) vulnerabilities occupy one of the first places in terms of frequency among the vulnerabilities found in WordPress plugins. These vulnerabilities occur when data from a user is not sufficiently cleaned before being displayed on site pages, which allows attackers to inject malicious code such as JavaScript and execute it in visitors’ browsers. XSS attacks can lead to theft of user data, hijacking of sessions, modification of page content, and other types of malicious activity
