Vite Plus

launch-editor allows users to open files with line numbers in editor from Node.js. Prior to 2.14.2, launch-editor did not escape % on Windows when passing an argument to cmd. When an environment variable contained a malicious value, it was possible that that content to be executed. This vulnerability is fixed in 2.14.2.

Vite is a frontend tooling framework for JavaScript. From 8.2.0 until 8.2.4 and 8.3.3, the first 4 bytes of files outside of server.fs setting can be returned to the browser by a request containing ?vite-wasm-instance. Requests containing the ?vite-wasm-instance query are handled by the internal Wasm plugin's load hook. The hook removes the query and reads the resulting path directly from disk, but the server.fs checks were not applied. After reading the file, Vite attempts to parse it as WebAssembly. When that parse fails, Node and deno throws an error that contains the first 4 bytes of the file. This vulnerability is fixed in 8.2.4 and 8.3.3.

launch-editor allows users to open files with line numbers in editor from Node.js. Prior to 2.14.2, launch-editor-middleware processes an attacker-controlled Windows file argument where the file argument ends in a parent-directory component plus a line-and-column suffix: the path is resolved while the suffix is still present, and launch-editor removes the suffix before its existsSync check, leaving the existing parent directory for existsSync and allowing the attacker-controlled file argument to pass filename existence validation without requiring the malicious filename to exist. The bypass can lead to OS command injection when combined with the separately described Windows percent-expansion flaw. This issue is fixed in version 2.14.2.

Vite is a frontend tooling framework for JavaScript. Prior to 6.4.4, 7.3.7, 8.1.6, 8.2.4, and 8.3.3, import analysis can record a root-relative browser URL in safeModulePaths instead of the cleaned resolved module identifier. On a network-accessible, non-Windows development server, an imported project file whose URL matches an absolute host path can authorize a later raw-filesystem request for that host file, provided server.fs.deny does not block it. The request can disclose the matching file outside the project root, but it does not allow arbitrary path traversal because the host path must correspond to a project-relative URL authorized by the application graph. This issue is fixed in versions 6.4.4, 7.3.7, 8.1.6, 8.2.4, and 8.3.3.

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.
