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
TalkTalk 3.3.6 Android App contains improper access control vulnerabilities in multiple API endpoints. By modifying request parameters, attackers may obtain sensitive user information (such as device identifiers and birthdays) and access private group information, including join credentials. Successful exploitation may result in privacy breaches and unauthorized access to restricted resources.

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

The TalkTalk Android app version 3.3.6 contains improper access control vulnerabilities in multiple API endpoints. Attackers can exploit these vulnerabilities by modifying request parameters to access sensitive user information (device identifiers, birthdays) and private group data including join credentials without proper authorization. This represents classic broken access control (likely IDOR) where the application fails to validate that the requesting user has permission to access the requested resources.

MitigationImplement robust authorization checks on all API endpoints to verify user permissions before returning any data, and validate that users can only access resources they own or are explicitly authorized to view.

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 if TalkTalk Android app is installed
    Check device application list or use ADB command: 'adb shell pm list packages | grep talktalk' to list installed packages
    Affected if The TalkTalk app package is found on the device
  2. Verify installed app version
    Use ADB: 'adb shell dumpsys package com.talktalk.android | grep versionName' or check app info in device Settings > Apps > TalkTalk
    Affected if Version is 3.3.6 or lower (any version below current patched release)
  3. Confirm API endpoint access (requires authorization/sandbox testing)
    If you are testing your own app deployment or have authorized access, intercept API traffic using a proxy and attempt to access user data endpoints with modified user identifiers
    Affected if API requests return sensitive data (device identifiers, birthdays, group credentials) when requesting other users' resources without proper authorization headers
  4. Check for exposed sensitive data in API responses
    Review API responses from the app for presence of fields like device identifiers, birthdates, or private group join credentials that should not be accessible
    Affected if API responses contain data belonging to other users or unauthorized sensitive fields

You are affected if the TalkTalk Android app version 3.3.6 or lower is installed and API endpoints allow unauthorized access to other users' sensitive information without proper authorization validation.
