dbcve checksWork through these to decide whether this CVE applies to you.
-
Verify Microsoft Teams for Android is installedOpen Settings > Apps on the Android device and look for Microsoft Teams in the app list, or check if the Teams app icon exists on the home screen or app drawerAffected if Microsoft Teams for Android is present on the device
-
Determine the installed Teams versionGo to Settings > Apps > Microsoft Teams > App info, or open the Teams app and navigate to Settings > About, to view the version number displayedAffected if The displayed version number is less than 1.0.76.2026111302
-
Compare version against affected rangeCompare your installed version number (for example, 1.0.76.2026111301 or any earlier version) to the affected threshold 1.0.76.2026111302Affected if The installed version starts with 1.0.76 and is numerically lower than 2026111302, or is any version prior to 1.0.76.2026111302
-
Confirm active usage of TeamsCheck if the Teams app has been used recently or contains conversation history, files, or meeting dataAffected if The app is actively used and contains sensitive data such as chat messages, shared files, or meeting content
If Microsoft Teams for Android is installed with a version lower than 1.0.76.2026111302 and contains or displays user-generated content, the environment is affected by this injection vulnerability.
