Who should care

Apple iOS fleet owners, MDM and mobile endpoint administrators, security teams managing iPhone devices, and any organization still running iOS builds before 10.2.

Technical summary

The vulnerability is described as a sandbox protection bypass in WebSheet, with unspecified exploitation vectors. NVD metadata shows CVSS 3.0 vector AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H, indicating a network-reachable issue requiring no privileges or user interaction and with high potential impact. The record’s affected-version data identifies iPhone OS/iOS versions up to 10.1.1 as vulnerable, while the narrative description says iOS before 10.2.

Defensive priority

Urgent. This is a critical, no-privileges, no-user-interaction issue with high confidentiality, integrity, and availability impact; affected devices should be prioritized for patching and inventory verification.

Recommended defensive actions

  • Update affected Apple devices to iOS 10.2 or later as soon as possible.
  • Use MDM or endpoint inventory to identify devices still running pre-10.2 builds, including those on 10.1.1 and earlier.
  • Treat any device exposed to untrusted web content as higher priority until it is confirmed patched.
  • Review Apple’s vendor advisory reference (HT207422) and the NVD record to confirm the applicable remediation guidance for your fleet.

All statements are based on the supplied CVE description, NVD metadata, and the listed Apple vendor advisory reference.
