Can you explain this vulnerability to me?

CVE-2026-26959 is a vulnerability in ADB Explorer, a Windows UI for ADB, where versions 0.9.26020 and below do not validate the integrity or authenticity of the ADB binary path specified in the ManualAdbPath setting before executing it.

This allows an attacker to craft a malicious settings file (App.txt) that points ManualAdbPath to an arbitrary executable. When a victim launches the application with a command-line argument directing it to the malicious configuration directory, the application executes the arbitrary executable with the privileges of the current user.

The vulnerability can be exploited through social engineering, such as distributing a shortcut bundled with the crafted settings file in an archive, causing remote code execution (RCE) upon application startup.

This issue was fixed in version 0.9.26021 by adding SHA-256 verification of the ADB executable against a trusted list to ensure file integrity and prevent tampering.

How can this vulnerability be detected on my network or system? Can you suggest some commands?

What immediate steps should I take to mitigate this vulnerability?

The immediate and most effective mitigation is to upgrade ADB-Explorer to version 0.9.26021 or later, which includes a security patch that verifies the integrity and authenticity of the ADB executable using SHA-256 hash checks.

Additional mitigation steps include:

• Do not run ADB-Explorer with untrusted or unknown configuration directories or App.txt files, especially those received from unverified sources.
• Avoid launching ADB-Explorer with command-line arguments pointing to directories containing suspicious or untrusted settings files.
• Manually verify the ManualAdbPath setting in App.txt files to ensure it points to legitimate ADB binaries.
• Implement endpoint security controls to detect and block execution of unauthorized binaries.

The patched version also improves security by storing temporary drag files in a safer location and requiring explicit arguments for the settings file path, reducing attack surface.
