CVE-2025-30430
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 · uneditedThis issue was addressed through improved state management. This issue is fixed in iOS 18.4 and iPadOS 18.4, macOS Sequoia 15.4, visionOS 2.4, watchOS 11.4. Password autofill may fill in passwords after failing authentication.
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 confidenceA state management vulnerability in Apple's password autofill mechanism allows passwords to be automatically filled even after authentication has failed. This creates a critical authentication bypass where the autofill feature does not properly validate the authentication state before populating credentials.

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 versionGo to Settings > General > About and look at the Software Version field. Alternatively, use Finder (iTunes) or run 'nsget -ipccommand DeviceInfo' via idevicesyslog on a connected device.Affected if The version is less than 18.4 (e.g., 18.3.x, 18.2.x, earlier) AND password autofill is enabled in Settings > Passwords > Password Options.
-
Check iPadOS versionGo to Settings > General > About and look at the Software Version field. On Mac, you can also check via Finder or idevicesyslog.Affected if The version is less than 18.4 AND password autofill is enabled in Settings > Passwords > Password Options.
-
Check macOS versionClick the Apple menu > About This Mac. The version number appears below the macOS name. You can also run 'sw_vers' in Terminal.Affected if The version is 15.0, 15.1, 15.2, or 15.3 (any version >= 15.0 but < 15.4) AND password autofill is enabled in System Settings > Passwords > Password Options.
-
Check visionOS versionGo to Settings > About. The version is listed under visionOS version. You can also check via Xcode device info.Affected if The version is less than 2.4 AND password autofill is enabled in Settings > Passwords > Password Options.
You are affected if your device runs any version less than the fixed release (iOS/iPadOS 18.4, macOS 15.4, visionOS 2.4) AND has password autofill functionality enabled.
