# HeyCyan Android app: cleartext network traffic may expose sensitive information

HeyCyan App 1.0.103 for Android has a weakness in its Network Security Configuration in AndroidManifest.xml that allows sensitive information to be sent in cleartext. A remote attacker who positions themselves on the network path could read that data, though the sources say exploitation is highly complex and difficult.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Decompile or open the app's `AndroidManifest.xml` and check whether `android:usesCleartextTraffic` is set to `true` or a `network_security_config` file permits cleartext domains
- Check the app's version with the Android package manager; the affected version is `1.0.103`

## Fix

- unknown: the sources report no vendor response and no patched version; watch the app's store listing for an update

## Timeline

- 2026-10-26T02:39:11+00:00 nvd https://nvd.nist.gov/vuln/detail/CVE-2026-116105

## From the sources

A weakness has been identified in HeyCyan App 1.0.103 on Android. Affected is an unknown function of the file AndroidManifest.xml of the component Network Security Configuration. Executing a manipulation can lead to cleartext transmission of sensitive information. The attack can be launched remotely. The attack requires a high level of complexity. The exploitability is told to be difficult. The vendor was contacted early about this disclosure but did not respond in any way.
