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
The PhonePe wallet (aka com.PhonePe.app) application 3.0.6 through 3.3.26 for Android might allow attackers to perform Account Takeover attacks by exploiting its Forgot Password feature. NOTE: the vendor says that, to exploit this, the user has to explicitly install a malicious app and provide accessibility permission to the malicious app, that the Android platform provides fair warnings to the users before turning on accessibility for any application, and that it believes it is similar to installing malicious keyboards, or malicious apps taking screenshots

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 PhonePe Android wallet application versions 3.0.6-3.3.26 contains an Account Takeover vulnerability in its Forgot Password feature. A malicious app granted accessibility permissions can likely intercept sensitive data during the password reset process, allowing attackers to capture reset tokens or credentials.

MitigationImplement defense-in-depth controls: detect and block accessibility services during password reset flows, add device binding or biometric verification for sensitive operations, and implement anomaly detection for suspicious account recovery requests.

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. Confirm PhonePe app is installed
    Navigate to Settings > Apps on the Android device and locate the PhonePe app in the app list, or run: adb shell pm list packages | grep phonepe
    Affected if The PhonePe application is present on the device
  2. Check installed PhonePe version
    In Settings > Apps > PhonePe, view the App info to see the version number, or run: adb shell dumpsys package com.phonepe.app | grep versionName
    Affected if The installed version falls within 3.0.6 to 3.3.26 inclusive
  3. Review granted accessibility permissions
    Navigate to Settings > Accessibility > Accessibility services and list all apps with accessibility permissions enabled, or run: adb shell settings get secure enabled_accessibility_services
    Affected if Any third-party app other than system accessibility services has been granted accessibility permissions
  4. Inspect installed apps for suspicious packages
    Review the list of installed apps (Settings > Apps > See all apps) for any unfamiliar or malicious-looking applications that could have been used to exploit the accessibility permission
    Affected if Unknown or untrusted apps with accessibility permissions are present on the device

A user is affected if PhonePe version 3.0.6 through 3.3.26 is installed AND any third-party app has been granted accessibility permissions on the device.
