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

Vulnerability from nvd – Published: 2026-05-07 18:14 – Updated: 2026-05-09 03:55

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.
Severity

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.

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.
