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 · unedited
An issue was discovered in certain Apple products. iOS before 10.2 is affected. The issue involves the "WebKit" component, which allows XSS attacks against Safari.

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

A cross-site scripting (XSS) vulnerability exists in the WebKit component of Safari on iOS versions prior to 10.2. The vulnerability allows attackers to inject malicious scripts through web pages, potentially compromising user sessions or stealing sensitive data.

MitigationUpdate iOS devices to version 10.2 or later to apply Apple's security patch. Until updated, restrict Safari usage and avoid untrusted websites.

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. Identify the iOS device
    Confirm the device is an iPhone, iPad, or iPod touch running Safari as the browser
    Affected if Device is any iOS-based Apple mobile device
  2. Check iOS version number
    Go to Settings > General > About > Version on the iOS device to view the installed iOS version
    Affected if Version displays 10.1.1 or lower
  3. Verify Safari is the browser
    Confirm Safari is the default browser used for web browsing on the device
    Affected if Safari is actively used for web browsing
  4. Confirm WebKit is the rendering engine
    Safari on iOS uses WebKit as its rendering engine by default - no configuration needed
    Affected if Safari is enabled and used for web browsing

The device is affected if it is running iOS version 10.1.1 or lower and uses Safari for web browsing, since the WebKit component contains the XSS vulnerability in those versions.
