This is due to the plugin's admin-shell.js registering a global message event listener without origin validation (missing event.origin check) and directly passing user-controlled URLs to window.open() without URL scheme validation. This makes it possible for unauthenticated attackers to execute arbitrary JavaScript in the context of an authenticated administrator's session by tricking them into visiting a malicious website that sends crafted postMessage payloads to the plugin's admin page."},{"lang":"es","value":"El plugin RSS Aggregator – RSS Import, News Feeds, Feed to Post y Autoblogging para WordPress es vulnerable a cross-site scripting basado en DOM a través de postMessage en todas las versiones hasta la 5.0.11, inclusive.
