3DescriptionGitHub Advisory
Notepad++ is a free and open-source source code editor. An Unsafe Search Path vulnerability (CWE-426) exists in versions prior to 8.9.2 when launching Windows Explorer without an absolute executable path. This may allow execution of a malicious explorer.exe if an attacker can control the process working directory. Under certain conditions, this could lead to arbitrary code execution in the context of the running application. Version 8.9.2 patches the issue.
AnalysisAI
Notepad++ versions before 8.9.2 allow local code execution through an unsafe search path vulnerability that permits attackers to hijack the Windows Explorer executable if they control the process working directory. A user with local access running the affected application could be tricked into executing a malicious explorer.exe, leading to arbitrary code execution with application privileges. Public exploit code exists for this vulnerability and no patch is currently available.
