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
Implicit intent hijacking vulnerability in UPHelper library prior to version 4.0.0 allows local attackers to access sensitive information via implicit intent.

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

This is an implicit intent hijacking vulnerability in the UPHelper library for Android. Implicit intents can be intercepted by other local applications if not properly secured with explicit intents or proper permission protections, allowing attackers to potentially receive sensitive data meant for the legitimate application.

MitigationUpgrade UPHelper library to version 4.0.0 or later which implements proper intent handling. Review all intent usage in the application to ensure explicit intents are used for sensitive operations.

Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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. Locate UPHelper library in the project
    Search your Android project dependencies (build.gradle, gradle.lock, libs folder, or Maven pom.xml) for any 'UPHelper', 'uphelper', or Samsung-related library references
    Affected if UPHelper library is found in the project's dependency declarations
  2. Identify the installed UPHelper version
    Examine the declared version in your dependency file (e.g., 'implementation "com.samsung.android:uphelper:x.x.x"' in build.gradle) or check the library JAR/aar file metadata
    Affected if The version number is below 4.0.0 or no version is specified (implying an older release)
  3. Search for implicit intent usage in the codebase
    Review source code for Intent constructor calls without specifying a component (e.g., new Intent(Intent.ACTION_VIEW) without setComponent, setClass, or setClassName) used to pass data
    Affected if The application code creates implicit intents to send sensitive data between app components
  4. Inspect AndroidManifest.xml for intent filters
    Examine the AndroidManifest.xml file for <intent-filter> declarations on activities, services, or broadcast receivers that handle sensitive operations
    Affected if Components receiving sensitive data via intents have intent-filters defined, making them potentially reachable by other local applications
  5. Check for exported components handling sensitive intents
    In AndroidManifest.xml, review components that handle incoming intents for the 'android:exported' attribute value and any permission requirements (android:permission)
    Affected if Components processing sensitive intent data are exported without a permission protection attribute

The environment is affected if the UPHelper library version is below 4.0.0 AND the application uses implicit intents to transmit sensitive data between components.

dbcve · scoped
Upgrade available Upgrade to 4.0.0 or later
Fixed in 4.0.0
Interim mitigation

Upgrade UPHelper library to version 4.0.0 or later which implements proper intent handling. Review all intent usage in the application to ensure explicit intents are used for sensitive operations.

Recommended fix High confidence

Uphelper Library version 4.0.0

  1. 1. Open your project's build.gradle (module-level) file
  2. 2. Locate the Uphelper Library dependency declaration
  3. 3. Update the version number to 4.0.0 or later (e.g., implementation 'com.samsung.android:uphelper:4.0.0')
  4. 4. Sync your Gradle files to download the updated library
  5. 5. Rebuild and test your application to ensure the upgrade does not introduce regressions
Caveat Review the library's release notes for any API changes or deprecated methods that may affect your implementation
