CVE-2023-37513
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 confidenceThis is an iOS information disclosure vulnerability where the app fails to apply a blur effect or secure overlay when entering the background, causing sensitive screen contents to be captured in the iOS task switcher snapshot. The issue stems from missing implementation of UIApplication delegate callbacks (applicationWillResignActive or applicationDidEnterBackground) to obscure the UI before the snapshot is taken.

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 installed version of Hcltech Traveler To DoOpen the App Store app, go to your profile, tap 'Purchased' and find Hcltech Traveler To Do to view the installed version, or check within the app's settings or about sectionAffected if The displayed version is lower than 12.0.6
-
Confirm app is present on deviceLocate the Hcltech Traveler To Do icon on your iOS device home screen or in the app libraryAffected if The app is installed and visible in the app list
-
Test background snapshot behaviorOpen Hcltech Traveler To Do, ensure sensitive content is displayed on screen, then press the home button or swipe up to switch to another app, then activate the task switcher to view the snapshotAffected if The task switcher shows unobscured sensitive content from the app rather than a blur effect or secure overlay covering the screen
You are affected if Hcltech Traveler To Do version is below 12.0.6 and the task switcher snapshot displays unblurred sensitive content when the app enters 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 UIApplication delegate methods to add a UIVisualEffectView with blur or a secure cover view before the app enters background state, ensuring sensitive data is not exposed in the task switcher snapshot.
12.0.6
- Open the App Store on the iOS device
- Search for 'HCL Traveler To Do' or navigate to the app in the App Store
- Tap 'Update' to install version 12.0.6 or later
