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 menu > About Safari. Compare the version number to the affected range (< 26.5.2).
    Affected if Safari version is less than 26.5.2 on macOS
  2. Check Safari version on iOS/iPadOS
    Open Settings app, go to Safari > About. Compare the version number to the affected range (< 26.5.2).
    Affected if Safari version is less than 26.5.2 on iOS or iPadOS
  3. Check macOS version
    Click Apple menu > About This Mac. The vulnerability applies to macOS >= 26.0 and < 26.5.2.
    Affected if macOS version is 26.0 or higher but Safari is below 26.5.2
  4. Confirm browser is used for web navigation
    The vulnerability triggers when visiting a malicious website. If Safari with a vulnerable version is used for browsing, the permission restriction flaw is present.
    Affected if Safari version is below 26.5.2 and the browser is used to visit websites

A user is affected if their Safari browser version is below 26.5.2 on any Apple platform, or if they are running macOS 26.0-26.5.2 with an unpatched Safari.
