Why these techniques?

The stored XSS vulnerability allows high-privilege users to inject unsanitized HTML/JavaScript via plugin settings, bypassing unfiltered_html restrictions (e.g., in multisite), enabling exploitation of public-facing WordPress applications, drive-by compromises via malicious content in posts, client-side code execution in visitors' browsers, and defense evasion through capability bypass.
