CVE-2026-38972: Rizonesoft notepad3 uncontrolled search path element vulnerability

Rizonesoft · Notepad3

Notepad3 through 6.25.822.1 contains a DLL search-order hijacking vulnerability in the About-dialog code path in src/Notepad3.c. The application calls LoadLibrary(L"MSFTEDIT.DLL") with a bare DLL name, which allows a local attacker to place a malicious MSFTEDIT.DLL in the application directory or another preferred DLL search location and achieve arbitrary code execution in the context of the user when the About dialog is opened.
