CVE-2025-15556 3 Notepad++, Notepad-plus-plus, Notepad Plus Plus 3 Notepad++, Notepad++, Notepad++ 2026-02-04 N/A
Notepad++ versions prior to 8.8.9, when using the WinGUp updater, contain an update integrity verification vulnerability where downloaded update metadata and installers are not cryptographically verified. An attacker able to intercept or redirect update traffic can cause the updater to download and execute an attacker-controlled installer, resulting in arbitrary code execution with the privileges of the user.
CVE-2025-49144 2 Notepad++, Notepad Plus Plus 2 Notepad++, Notepad++ 2025-12-24 7.3 High
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.
