CVE-2026-27615Public exploit

Code execution via unchecked UNC binary path

Published Feb 25, 2026 · Updated Feb 25, 2026

Path traversal in Alex4SSB ADB Explorer before Beta 0.9.26022 allows attackers to execute code through a crafted settings file. ADBService.VerifyAdbVersion accepts ManualAdbPath from App.txt without rejecting UNC paths, verifies a share-hosted ADB binary, and executes that path while later ADB calls reuse it without another integrity check. Exploitation requires a victim to launch a shortcut that selects the attacker-supplied App.txt and allows arbitrary code to run with the victim's privileges after the share-hosted binary is replaced.
