CVE-2024-44127
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 17.7 and iPadOS 17.7, iOS 18 and iPadOS 18. Private Browsing tabs may be accessed without 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 · moderate confidenceThis is an authentication bypass vulnerability in iOS and iPadOS Safari where Private Browsing tabs can be accessed without requiring biometric or passcode authentication. The root cause was improper state management that allowed the private browsing state to be bypassed, potentially exposing sensitive browsing activity to unauthorized users who gain physical access to an unlocked device.

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 the iOS or iPadOS version installed on the deviceOn the device, go to Settings > General > About > Version. Alternatively, if managed via MDM, query the device for the OSVersion or ProductVersion attribute.Affected if The version number is less than 17.7 (for example, 17.6.1, 17.5, etc.)
-
Identify the device model and confirm it is a supported iPhone or iPadCheck Settings > General > About > Model Name to confirm the device model.Affected if The device is an iPhone or iPad running a version of iOS or iPadOS less than 17.7
-
Verify if the device has biometric or passcode authentication enabledCheck Settings > Face ID & Passcode (or Touch ID & Passcode) to see if a passcode is set and biometric authentication is enrolled.Affected if The device runs a vulnerable iOS/iPadOS version AND has passcode/biometric enabled, but Private Browsing tabs can still be accessed without re-authentication on that version
The device is affected if it is running iOS or iPadOS version 17.6 or earlier, since those versions contain the improper state management that allows Private Browsing tabs to be accessed without biometric or passcode re-authentication.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped17.7
Update iOS/iPadOS devices to version 17.7 or 18 or later to receive the fix. Organizations should ensure automatic updates are enabled or deploy the security update through their mobile device management (MDM) solution.
iOS 17.7 / iPadOS 17.7 or iOS 18 / iPadOS 18
- 1. Back up your device data to iCloud or a computer
- 2. Ensure your device is connected to Wi-Fi and plugged into power
- 3. Go to Settings > General > Software Update
- 4. If iOS 17.7 or iOS 18 update is available, tap 'Update'
- 5. Wait for the download and installation to complete (this may take several minutes)
- 6. After the device restarts, verify the update by checking Settings > General > About > Software Version
