    CVE-2026-42214 (GCVE-0-2026-42214)

    Vulnerability from cvelistv5 – Published: 2026-05-07 18:14 – Updated: 2026-05-09 03:55
    VLAI
    Title
    Improper Control of Generation of Code ('Code Injection') in dail8859/NotepadNext
    Summary
    Notepad Next is a cross-platform, reimplementation of Notepad++. Prior to version 0.14, NotepadNext's detectLanguageFromExtension() function interpolates a file's extension directly into a Lua script without sanitization. An attacker can craft a filename whose extension contains Lua code, which executes automatically when the victim opens the file in NotepadNext. Because luaL_openlibs() is called unconditionally, the full os, io, and package libraries are available to the injected code, enabling arbitrary command execution. This issue has been patched in version 0.14.

    Title
    Potential heap-based buffer over-read vulnerability in NotepadNext
    Summary
    Out-of-bounds Read vulnerability in dail8859 NotepadNext (src/lua/src modules). This vulnerability is associated with program files lparser.C. This issue affects NotepadNext: through v0.11. The singlevar() in lparser.c lacks a certain luaK_exp2anyregup call, leading to a heap-based buffer over-read that might affect a system that compiles untrusted Lua code.
