File Manager Application: Improper Export of Android Application Components
CVE-2026-18994 is a high-severity improper export of android application components vulnerability in File Manager Application from Lenovo, with a CVSS 3.1 base score of 7.1 out of 10. It can be exploited with local access to the system by an attacker with a low-privileged account, without any action from a user. The record lists version 9.8.1.77 as the first without the flaw, so updating File Manager Application to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.14% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.

The underlying weakness: Improper Export of Android Application Components
The Android application exports a component for use by other applications, but does not properly restrict which applications can launch the component or access the data it contains.
How developers prevent this class of flaw
- If they do not need to be shared by other applications, explicitly mark components with android:exported=false in the application manifest.
- If you only intend to use exported components between related apps under your control, use android:protectionLevel=signature in the xml manifest to restrict access to applications signed by you.
- Limit Content Provider permissions (read/write) as appropriate.
