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.
-
Check iOS version installed on the deviceGo to Settings > General > About > Version, or use Xcode/Apple Configurator to read the installed iOS versionAffected if The version displayed is 12.1.2 or earlier (less than 12.1.3)
-
Verify if Password AutoFill is enabledNavigate to Settings > Passwords & Accounts > AutoFill Passwords, or check Settings > Safari > AutoFill > PasswordsAffected if AutoFill Passwords is turned ON and the device uses Keychain or third-party password managers for autofill
-
Confirm Keychain password storage is in useCheck Settings > Passwords & Accounts > Website & App Passwords (requires authentication), or verify Safari/app autofill is linked to stored credentialsAffected if Any passwords are stored and available for autofill on the device
The environment is affected if the iOS version is below 12.1.3 and Password AutoFill is enabled with stored credentials available for autofill.
