CVE-2026-27615 is a path traversal vulnerability categorized under CWE-40 and CWE-829 affecting the ADB-Explorer application by Alex4SSB on Windows platforms. The vulnerability arises because the application allows the 'ManualAdbPath' configuration variable, which specifies the path to the ADB binary, to be set to a Universal Naming Convention (UNC) path. This means an attacker can configure the application to execute a binary located on a remote network share controlled by the attacker. Since the application executes this binary with the privileges of the current user, this leads to remote code execution (RCE). The attack vector involves convincing a user to run a shortcut or launch the app with a malicious 'App.txt' settings file that sets the 'ManualAdbPath' to the attacker's UNC share. This can be delivered via social engineering, such as through an archive file containing the malicious shortcut. The vulnerability affects all versions before Beta 0.9.26022, which contains the fix. The CVSS 4.0 score is 8.8 (high), reflecting the ease of exploitation with user interaction, no privileges required, and the high impact on confidentiality, integrity, and availability. No public exploits are known yet, but the potential for significant damage exists due to the ability to execute arbitrary code remotely.

The impact of CVE-2026-27615 is significant for organizations using vulnerable versions of ADB-Explorer on Windows. Successful exploitation allows attackers to execute arbitrary code remotely with the same privileges as the user running the application, potentially leading to full system compromise. This can result in data theft, installation of persistent malware, lateral movement within networks, and disruption of operations. Since ADB-Explorer is a tool used for Android Debug Bridge (ADB) operations, it is likely employed by developers, testers, and IT administrators, making these groups particularly at risk. The vulnerability could be exploited in targeted attacks or through phishing campaigns distributing malicious shortcuts or archives. The requirement for user interaction limits mass exploitation but does not eliminate risk, especially in environments where users may run untrusted files. Organizations with sensitive data or critical infrastructure using this tool must prioritize remediation to avoid severe confidentiality, integrity, and availability breaches.

To mitigate CVE-2026-27615, organizations should immediately upgrade ADB-Explorer to version Beta 0.9.26022 or later, where the vulnerability is fixed. Until the update is applied, users should avoid running shortcuts or configuration files from untrusted sources that could manipulate the 'ManualAdbPath' setting. Implement strict controls on file downloads and email attachments to reduce the risk of social engineering attacks delivering malicious archives or shortcuts. Employ endpoint protection solutions capable of detecting suspicious execution from UNC paths. Network segmentation and restricting SMB/UNC access to only trusted servers can reduce exposure to malicious network shares. Additionally, educate users about the risks of running unknown shortcuts or configuration files and enforce the principle of least privilege to limit the impact if exploitation occurs. Monitoring logs for unusual ADB-Explorer executions or network share accesses can help detect exploitation attempts early.
