Idea Tab Pro TB373FU: Improper Export of Android Application Components
CVE-2026-116633 is a high-severity improper export of android application components vulnerability in Idea Tab Pro TB373FU 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 unauthenticated attacker, but only if a user takes part, for example by opening a link or file. The record lists version 17.5.10.107 as the first without the flaw, so updating Idea Tab Pro TB373FU to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.13% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update Idea Tab Pro TB373FU to 17.5.10.107 or a later version.
- Update Lenovo Tab One TB305FU to 17.0.10.324 or a later version.
- Update Lenovo Tab One TB305XU to 17.0.10.318 or a later version.
- Because the attack needs a user to take part, warn users about unexpected links and files related to this product until it is patched.

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.
