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 checksWork through these to decide whether this CVE applies to you.
-
Identify the Apple productDetermine whether the device is running Apple Safari (macOS or iOS), iOS, iPadOS, or macOS. On macOS, you can check System Settings > General > About or run 'sw_vers' in Terminal.Affected if Any of the affected Apple products: Safari, iOS, iPadOS, or macOS
-
Check the installed versionFor Safari on macOS: Open Safari > About Safari. For iOS/iPadOS: Open Settings > General > About > Software Version. For macOS: Run 'sw_vers -productVersion' in Terminal or check System Settings > General > About.Affected if The detected version is revealed for comparison against vulnerable ranges
-
Compare against vulnerable version rangeReview the version number obtained and compare against the affected ranges: Safari < 26.5.2, iOS < 26.5.2, iPadOS < 26.5.2, macOS >= 26.0 and < 26.5.2Affected if The installed version falls within the vulnerable range: Safari, iOS, or iPadOS earlier than 26.5.2, or macOS version 26.0 through 26.5.1
The environment is affected if Safari, iOS, iPadOS, or macOS is running a version lower than 26.5.2 (or macOS in the range 26.0 to 26.5.1).
