Technical details

The plugin fails to sanitize the 'seopress_google_analytics_affiliate_tracking' setting (omitted entirely) and insufficiently escapes 'seopress_google_analytics_download_tracking' (only sanitize_text_field() applied) before interpolating them into inline Google Analytics JavaScript. An authenticated attacker with Subscriber-level access or above can inject arbitrary JavaScript that executes whenever users access affected pages. A fix is available in versions after 10.3.
