In the meantime, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as a temporary mitigation strategy. These tools can help detect and prevent attempts to exploit this vulnerability.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Overview CVE-2025-31208 is a critical vulnerability that affects several operating systems including watchOS, macOS, tvOS, iPadOS, iOS, and visionOS.
