CVE-2023-37512
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 · uneditedWhen the app is put to the background and the user goes to the task switcher of iOS, the app snapshot is not blurred which may reveal sensitive information.
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 confidenceWhen an iOS app enters the background, iOS captures a snapshot of the current view for display in the task switcher. This CVE occurs when the app fails to blur or hide sensitive UI elements before the snapshot is captured, allowing confidential data to be visible to anyone accessing the iOS app switcher.

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.
-
Verify Hcltech Traveler Companion is installedCheck your iOS device for the presence of the Hcltech Traveler Companion app in the app library or on the home screenAffected if The app is not installed on the device
-
Identify installed app versionGo to iOS Settings > General > iPhone Storage, find Hcltech Traveler Companion, and note the version number displayedAffected if Version number is less than 12.0.6 (for example, 12.0.5, 12.0.0, or any version below 12.0.6)
-
Confirm affected conditionThe vulnerability exists if the app version is below 12.0.6 - this indicates the app was likely built before the fix was applied and may not include the blur overlay protection in the background lifecycle handlersAffected if Installed version is any version prior to 12.0.6, meaning the app could expose sensitive data in the iOS task switcher snapshot
A user is affected if Hcltech Traveler Companion is installed and the version is below 12.0.6, as earlier versions lack the blur overlay protection when the app enters the background.

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 · scoped12.0.6
Implement application lifecycle handlers (applicationWillResignActive, scenePhase changes, or UIApplicationDelegate methods) to apply a blur overlay or clear sensitive views before the app enters the background and the snapshot is taken.
Traveler Companion version 12.0.6
- Open the App Store on the iOS device
- Search for 'HCL Traveler Companion' or 'Traveler Companion'
- Locate the app in search results
- Tap 'Update' to install version 12.0.6 or later
- Alternatively, enable automatic app updates: go to Settings > App Store > turn on 'App Updates'
- After updating, verify the version by opening the App Store listing and confirming it shows version 12.0.6 or higher
