Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Check Safari version on macOS
    Open Safari, click Safari > About Safari to view the version number in the dialog window
    Affected if Version is earlier than 15.5 (for example, 15.4.x or earlier)
  2. Check macOS version
    Click Apple menu > About This Mac to view the macOS version
    Affected if macOS version is 12.0.0 through 12.3.x (12.4 and later are patched)
  3. Check iOS or iPadOS version on iPhone or iPad
    Go to Settings > General > About to view the iOS/iPadOS version number
    Affected if Version is earlier than 15.5 (for example, 15.4.x or earlier)
  4. Check tvOS version on Apple TV
    Go to Settings > General > About > Version to view the tvOS version
    Affected if Version is earlier than 15.5 (for example, 15.4.x or earlier)
  5. Check watchOS version on Apple Watch
    Open the Watch app on iPhone, go to General > About to view the watchOS version
    Affected if Version is earlier than 8.6 (for example, 8.5.x or earlier)

You are affected if Safari is below version 15.5, or if macOS is between 12.0.0 and 12.3.x, or if iOS/iPadOS/tvOS is below 15.5, or if watchOS is below 8.6, since the vulnerability exists in the WebKit rendering engine used by Safari and Safari-based browsers on those platforms.
