What is CVE-2026-26959?
CVE-2026-26959 is a high-severity code injection vulnerability in Alex4SSB ADB-Explorer, published on 19 Feb 2026. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.
Official description
ADB Explorer is a fluent UI for ADB on Windows. Versions 0.9.26020 and below fail to validate the integrity or authenticity of the ADB binary path specified in the ManualAdbPath setting before executing it, allowing arbitrary code execution with the privileges of the current user. An attacker can exploit this by crafting a malicious App.txt settings file that points ManualAdbPath to an arbitrary executable, then convincing a victim to launch the application with a command-line argument directing it to the malicious configuration directory. This vulnerability could be leveraged through social engineering tactics, such as distributing a shortcut bundled with a crafted settings file in an archive, resulting in RCE upon application startup. Thus issue has been fixed in version 0.9.26021.
