CVE-2025-49144 (GCVE-0-2025-49144)
Vulnerability from cvelistv5 – Published: 2025-06-23 19:01 – Updated: 2025-10-23 13:28
VLAI?
Summary
Notepad++ is a free and open-source source code editor. In versions 8.8.1 and prior, a privilege escalation vulnerability exists in the Notepad++ v8.8.1 installer that allows unprivileged users to gain SYSTEM-level privileges through insecure executable search paths. An attacker could use social engineering or clickjacking to trick users into downloading both the legitimate installer and a malicious executable to the same directory (typically Downloads folder - which is known as Vulnerable directory). Upon running the installer, the attack executes automatically with SYSTEM privileges. This issue has been fixed and will be released in version 8.8.2.

CVE-2025-49144 (GCVE-0-2025-49144)
Vulnerability from nvd – Published: 2025-06-23 19:01 – Updated: 2025-10-23 13:28
VLAI?
Summary
Notepad++ is a free and open-source source code editor. In versions 8.8.1 and prior, a privilege escalation vulnerability exists in the Notepad++ v8.8.1 installer that allows unprivileged users to gain SYSTEM-level privileges through insecure executable search paths. An attacker could use social engineering or clickjacking to trick users into downloading both the legitimate installer and a malicious executable to the same directory (typically Downloads folder - which is known as Vulnerable directory). Upon running the installer, the attack executes automatically with SYSTEM privileges. This issue has been fixed and will be released in version 8.8.2.
