A malicious user first requires local access and user interaction. Once these conditions are met, they can <a href=\"https:\/\/www.ameeba.com\/blog\/cve-2025-47986-universal-print-management-service-exploit-elevates-privileges\/\"  data-wpil-monitor-id=\"92309\">exploit the vulnerability to execute arbitrary code with elevated<\/a> privileges.

In the interim, utilizing a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide temporary mitigation. However, these measures will not remove the vulnerability but may help detect and prevent exploitation attempts.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Overview The CVE-2025-54111 is a critical vulnerability found in the Windows UI XAML Phone DatePickerFlyout feature.
