Security is paramount in plugin development. Always sanitize input using functions like sanitize_text_field and sanitize_email. Validate data before processing to prevent malicious submissions. Escape output with esc_html, esc_url, and esc_attr. Use nonces to verify request authenticity and prevent CSRF attacks. Check user capabilities with current_user_can before sensitive operations. Prepare database queries properly using wpdb prepare […]

Security should never be an afterthought in plugin development. Always sanitize user input using functions like sanitize_text_field() and validate data with isset() checks.
