Executive Summary

CVE-2026-30280 is an arbitrary file overwrite vulnerability found in the "Video player - Play All Videos" Android app version 1.0.135 by RAREPROB SOLUTIONS PRIVATE LIMITED. The flaw exists in the file import process within the component com.kaisquare.location.MainActivity, where insufficient security validation allows an attacker to manipulate the filename and content of imported files.

By exploiting path traversal techniques, an attacker can overwrite critical internal files in the app's internal storage. This can happen automatically when the victim opens a malicious app crafted by the attacker.
