## What is CVE-2016-6910?

CVE-2016-6910 is a medium-severity vulnerability in Google Android, published on 23 Dec 2016. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.

### Official description

The non-existent notification listener vulnerability was introduced in the initial Android 5.0.2 builds for the Samsung Galaxy S6 Edge devices, but the vulnerability can persist on the device even after the device has been upgraded to an Android 5.1.1 or 6.0.1 build. The vulnerable system app gives a non-existent app the ability to read the notifications from the device, which a third-party app can utilize if it uses a package name of com.samsung.android.app.portalservicewidget. This vulnerability allows an unprivileged third-party app to obtain the text of the user's notifications, which tend to contain personal data.

Weakness: CWE-200 (Exposure of Sensitive Information to an Unauthorized Actor)

What it is: CVE-2016-6910 is a medium-severity vulnerability in Google Android, published on 23 Dec 2016. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.
Exploitation: There is no known exploitation of CVE-2016-6910 in the wild and no public exploit code.

Affected product: Google Android. No package-level version data is available, so check the vendor advisory linked from the reference page.

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
