Technical details

Stored XSS vulnerability in shortcode attribute handling due to insufficient input sanitization and output escaping. WordPress's save-time wp_kses_post does not neutralize payloads delivered via shortcode attributes rather than raw HTML post content, allowing unescaped values to persist and execute on page render. Attack requires authenticated access at contributor level or above.
