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
A vulnerability in Okta Verify for iOS versions 9.25.1 (beta) and 9.27.0 (including beta) allows push notification responses through the iOS ContextExtension feature allowing the authentication to proceed regardless of the user’s selection. When a user long-presses the notification banner and selects an option, both options allow the authentication to succeed. The ContextExtension feature is one of several push mechanisms available when using Okta Verify Push on iOS devices. The vulnerable flows include: * When a user is presented with a notification on a locked screen, the user presses on the notification directly and selects their reply without unlocking the device; * When a user is presented with a notification on the home screen and drags the notification down and selects their reply; * When an Apple Watch is used to reply directly to a notification. A pre-condition for this vulnerability is that the user must have enrolled in Okta Verify while the Okta customer was using Okta Classic. This applies irrespective of whether the organization has since upgraded to Okta Identity Engine.

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 confidence

Okta Verify for iOS versions 9.25.1 and 9.27.0 contains an authentication bypass vulnerability in the iOS ContextExtension push notification handling. When users respond to push notifications (via locked screen, home screen drag-down, or Apple Watch), both approval and denial selections incorrectly allow authentication to succeed, bypassing user intent. The vulnerability only affects users who enrolled in Okta Verify while the organization was on Okta Classic, regardless of subsequent upgrades to Okta Identity Engine.

MitigationOrganizations should update Okta Verify to the latest patched version once released and identify users enrolled during Okta Classic era for potential re-enrollment to ensure the secure push flow is enforced. Until patch is available, consider alternative authentication methods.

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 Okta Verify iOS version
    Open the iOS Settings app, locate Okta Verify in the installed apps list, and view the version information displayed under the app name. Alternatively, open the App Store, search for Okta Verify, and check the version number listed on the app's store page.
    Affected if The installed version is 9.25.1 or 9.27.0 specifically.
  2. Determine enrollment era
    Verify whether the Okta organization was using Okta Classic or Okta Identity Engine at the time the user initially enrolled in Okta Verify. This information may be available in the user's Okta admin console under authentication policies or enrollment history, or by checking with the organization's Okta administrator about their migration status at the time of enrollment.
    Affected if The user enrolled in Okta Verify while the organization was on Okta Classic, regardless of any subsequent upgrades to Okta Identity Engine.
  3. Confirm iOS push notification usage
    Test the push notification authentication flow by triggering a login request that would send a push notification to the device. Observe whether the authentication completes successfully regardless of whether the user selects Approve or Deny on the lock screen, home screen notification, or Apple Watch.
    Affected if Authentication succeeds whether the user taps Approve or Deny in the push notification, indicating the bypass is active.
  4. Identify ContextExtension presence
    On the iOS device, go to Settings > Okta Verify > About or check the app's bundle contents for the presence of a ContextExtension component used for handling push notifications. This extension is responsible for processing the user's approval or denial response.
    Affected if The ContextExtension is present and handles push notification responses, which is the vulnerable component.

A user is affected if they have Okta Verify for iOS versions 9.25.1 or 9.27.0 AND enrolled while their organization was on Okta Classic, and they use push notification authentication.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Organizations should update Okta Verify to the latest patched version once released and identify users enrolled during Okta Classic era for potential re-enrollment to ensure the secure push flow is enforced. Until patch is available, consider alternative authentication methods.

Recommended fix Moderate confidence

A version subsequent to 9.27.0 (contact Okta support or check help.okta.com for the exact fixed release)

  1. 1. Update Okta Verify for iOS from the Apple App Store to the latest available version.
  2. 2. Verify that the updated version includes the fix for the push notification authentication bypass.
  3. 3. Confirm that users who enrolled during Okta Classic era have updated their Okta Verify app.
  4. 4. Test the push notification flow on iOS to ensure that 'Deny' correctly rejects authentication requests.
