CVE-2026-112944: Argument Injection

Description

launch-editor allows users to open files with line numbers in editor from Node.js. Prior to 2.14.2, when an attacker can create a filesystem entry beginning with plus or minus in the working directory, an affected editor is selected, and the path can remain relative or is converted to a relative WSL path, launchEditor forwards the path without forcing it to be interpreted as a positional filename. Editor option parsing then treats the attacker-controlled filename as a command-line flag, which can cause unintended file overwrite or arbitrary command execution by the selected editor. The affected editors are Vim and gVim, MacVim, Emacs and Emacsclient, and Notepad++ when a plugin exposes dangerous operations; WSL path conversion keeps Vite and newer middleware callers exposed. This issue is fixed in version 2.14.2.
