Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
A logic issue was addressed with improved state management. This issue is fixed in iOS 15.3 and iPadOS 15.3, watchOS 8.4, tvOS 15.3, Safari 15.3, macOS Monterey 12.2. Processing maliciously crafted web content may prevent Content Security Policy from being enforced.

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.

dbcve analysis · high confidence

A logic flaw in Apple's WebKit state management allows malicious web content to bypass Content Security Policy (CSP) enforcement. When processing specially crafted web content, the browser fails to properly apply CSP headers, potentially allowing XSS and data injection attacks.

MitigationUpdate affected Apple devices to iOS 15.3/iPadOS 15.3, watchOS 8.4, tvOS 15.3, Safari 15.3, or macOS Monterey 12.2 or later. Avoid browsing untrusted websites until patches are applied.

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, go to Safari menu > About Safari, or run `defaults read /Applications/Safari.app/Contents/Info CFBundleShortVersionString` in Terminal
    Affected if Version is lower than 15.3
  2. Check iOS version on iPhone
    Go to Settings > General > About on the device, or connect to Finder/iTunes to view the iOS version
    Affected if Version is lower than 15.3
  3. Check iPadOS version on iPad
    Go to Settings > General > About on the device
    Affected if Version is lower than 15.3
  4. Check macOS version
    Click Apple menu > About This Mac, or run `sw_vers -productVersion` in Terminal
    Affected if Version is 12.0.0 through 12.1.x (12.2 and later are not affected)
  5. Check tvOS version
    Go to Settings > General > About on Apple TV
    Affected if Version is lower than 15.3
  6. Check watchOS version
    Open Watch app on paired iPhone, go to My Watch > General > About, or go to Settings > General > About on Apple Watch
    Affected if Version is lower than 8.4
