About Alex4ssb Adb Explorer

CVE-2026-27615 affects Alex4ssb Adb Explorer, a product from Alex4ssb. Before acting, confirm where Alex4ssb Adb Explorer runs in your estate, who owns it and whether it is reachable from the internet, because exposure decides real risk more than the score alone.

What the flaw is

In plain terms: ADB Explorer is a fluent UI for ADB on Windows. In versions prior to Beta 0.9.26022, ADB-Explorer allows the `ManualAdbPath` settings variable, which determines the path of the ADB binary to be executed, to be set to a Universal Naming Convention (UNC) path in the application's settings file. This allows an attacker to set the binary's path to point to a remote network resource, hosted on an attacker-controlled network share, thus granting the attacker full control over the binary being executed by the app. An attacker may leverage this vulnerability to execute code remotely on a victim's machine with the privileges of the user running the app. Exploitation is made possible by convincing a victim to run a shortcut of the app that points to a custom `App.txt` settings file, which sets `ManualAdbPath` (for example, when downloaded in an archive file). Version Beta 0.9.26022 fixes the issue.

Based on its CVSS vector, the flaw needs local or adjacent access, needs no login, and relies on a user taking an action. Apply the vendor fix and confirm exposure on internet facing and business critical assets first.
