CVE-2026-1464
📋 TL;DR
An integer overflow vulnerability in the Apache Commons Compress TarUtils module used by AppManager allows attackers to cause denial of service or potentially execute arbitrary code by crafting malicious TAR archives. This affects all AppManager users running versions before 4.0.4.

⚠️ Risk & Real-World Impact
Worst Case
Remote code execution leading to complete system compromise if the integer overflow enables memory corruption that can be leveraged for arbitrary code execution.
Likely Case
Application crash or denial of service when processing specially crafted TAR archives, potentially disrupting AppManager functionality.
If Mitigated
Limited impact with proper input validation and memory protections, potentially reduced to application instability rather than compromise.
🎯 Exploit Status
Exploitation requires crafting malicious TAR archives and getting them processed by the vulnerable component. No public exploit code has been identified.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 4.0.4
Vendor Advisory: https://github.com/MuntashirAkon/AppManager/pull/1598
Restart Required: Yes
Instructions:
1. Update AppManager to version 4.0.4 or later from the official GitHub repository or trusted app store. 2. Restart the application after update. 3. Verify the update was successful by checking the version number.
🔧 Temporary Workarounds
Disable TAR archive processing
allPrevent AppManager from processing TAR archives if this functionality is not required
Not applicable - configuration change within AppManager settings
Use external TAR utilities
allConfigure AppManager to use external, trusted TAR utilities instead of the built-in vulnerable component
Configuration dependent on AppManager settings
🧯 If You Can't Patch
- Implement strict input validation for TAR archives before processing
- Use application sandboxing or containerization to limit potential impact
🔍 How to Verify
Check if Vulnerable:
Check AppManager version in app settings or via 'adb shell dumpsys package org.muntashirakon.AppManager | grep versionName'Check Version:
adb shell dumpsys package org.muntashirakon.AppManager | grep versionNameVerify Fix Applied:
Confirm AppManager version is 4.0.4 or higher using the same version check command📡 Detection & Monitoring
