What is CVE-2026-26208?
CVE-2026-26208 is a high-severity unsafe deserialization vulnerability in Alex4SSB ADB-Explorer, published on 13 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. Prior to Beta 0.9.26020, ADB Explorer is vulnerable to Insecure Deserialization leading to Remote Code Execution. The application attempts to deserialize the App.txt settings file using Newtonsoft.Json with TypeNameHandling set to Objects. This allows an attacker to supply a crafted JSON file containing a gadget chain (e.g., ObjectDataProvider) to execute arbitrary code when the application launches and subsequently saves its settings. This vulnerability is fixed in Beta 0.9.26020.
Weakness: CWE-502
