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 confidence

This is an iOS/iPadOS vulnerability where notifications marked for deletion are unexpectedly retained on the device due to a logging issue with improper data redaction. The flaw allows sensitive notification data to persist beyond the user's intended deletion action, creating a privacy exposure where deleted notifications may still be accessible.

MitigationApply the relevant iOS/iPadOS security update for your version (15.8.8, 16.7.16, 17.7.11, 18.7.8, or 26.4.2) to ensure notifications are properly deleted when requested.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Check iOS version
    Go to Settings > General > About and note the version number (e.g., 18.7.7, 26.3.1)
    Affected if Version is less than 18.7.8 OR falls between 26.0 and 26.4.2 inclusive
  2. Check iPadOS version
    Go to Settings > General > About and note the version number
    Affected if Version is less than 18.7.8 OR falls between 26.0 and 26.4.2 inclusive
  3. Identify if notifications were deleted
    Search the device for any notification history or logs that may contain old notification content
    Affected if Deleted notifications or notification data files exist on the device (the vulnerability causes them to be retained)

A user is affected if their device runs iOS/iPadOS version below 18.7.8 or between 26.0 and 26.4.2 and has notification data that was marked for deletion but may still be present.

Interim mitigation

Apply the relevant iOS/iPadOS security update for your version (15.8.8, 16.7.16, 17.7.11, 18.7.8, or 26.4.2) to ensure notifications are properly deleted when requested.

Recommended fix High confidence
