Vite Vulnerable to Arbitrary File Read via Vite Dev Server WebSocket
CVE-2026-39363 / GHSA-p9ff-h696-f583
More information

Summary
server.fscheck was not enforced to thefetchModulemethod that is exposed in Vite dev server's WebSocket.Impact
Only apps that match the following conditions are affected:
--hostorserver.hostconfig option)server.ws: falseArbitrary files on the server (development machine, CI environment, container, etc.) can be exposed.
Details
If it is possible to connect to the Vite dev server’s WebSocket without an
Originheader, an attacker can invokefetchModulevia the custom WebSocket eventvite:invokeand combinefile://...with?raw(or?inline) to retrieve the contents of arbitrary files on the server as a JavaScript string (e.g.,export default "...").The access control enforced in the HTTP request path (such as
server.fs.allow) is not applied to this WebSocket-based execution path.PoC
Start the dev server on the target
Example (used during validation with this repository):
pnpm -C playground/alias exec vite --host 0.0.0.0 --port 5173Confirm that access is blocked via the HTTP path (example: arbitrary file)
curl -i 'http://localhost:5173/@fs/etc/passwd?raw'Result:

403 Restricted(outside the allow list)Confirm that the same file can be retrieved via the WebSocket path
By connecting to the HMR WebSocket without an
Originheader and sending avite:invokerequest that callsfetchModulewith afile://...URL and?raw, the file contents are returned as a JavaScript module.Severity

vite:
server.fs.denybypass on Windows alternate pathsCVE-2026-53571 / GHSA-fx2h-pf6j-xcff
More information
Details
Summary
The contents of files that are specified by
server.fs.denycan be returned to the browser on Windows.Impact
Only apps that match the following conditions are affected:
--hostorserver.hostconfig option)server.fs.allowDetails
Vite’s dev server denies direct access to sensitive files through
server.fs.deny, including entries such as.env,.env.*, and*.{crt,pem}. However, on Windows, the deny logic does not correctly normalize NTFS ADS path forms before access checks are applied.Because of this, requests such as
/.env::$DATA?raware treated as allowed paths, while Windows resolves them to the original file's default data stream.Similar to that, Windows allows accessing a file using a different name with the 8.3 short name compatibility feature. Vite did not reject accessing files via them.
PoC

http://localhost:5173/.env::$DATA?rawExample expected result:

launch-editor: NTLMv2 hash disclosure via UNC path handling on Windows
CVE-2026-53632 / GHSA-v6wh-96g9-6wx3
More information
Details
Summary
The
launch-editorNPM package accesses arbitrary paths including Windows UNC paths. When a UNC path is opened, Windows automatically attempts NTLM authentication to the remote host, causing the user’s NTLMv2 password hash to be leaked to an attacker-controlled SMB server. This can result in credential compromise through offline hash cracking.Impact
If the following conditions are met, an attacker can get the NTLMv2 password hash on the computer that is using the
launch-editor:launch-editorlaunch-editoris runningThis would be a problem if the user password is too simple that it can be identified through offline hash cracking, potentially leading to further compromise of developer accounts or internal systems.
Details
launch-editoraccepts file paths without validating or restricting Windows UNC paths such as:On Windows systems, accessing a UNC path triggers an automatic NTLM authentication attempt to the remote SMB server. No user interaction or warning is required for this authentication attempt to occur.
If an attacker controls the SMB server referenced by the UNC path the victim’s NTLMv2 hash is transmitted to the attacker. The attacker can then capture the hash and perform offline password cracking. Successful cracking reveals the victim’s cleartext password.
The attacker could target a developer that uses a development server using
launch-editorto develop code locally, send them a link and grab their NTLMv2 hash.PoC
From the attacker side, we will setup an SMB server. I personally used Impacket's smbserver.py, but you could use something like Responder for this as well. For keeping it simple, we will use
smbserver.pyhere.First, let's create a directory to serve as an SMB share.
Then, start the SMB server.
Now, run any project that uses the launch-editor package. I have setup a simple "Hello world" project that uses Vite to do this. Then run the project locally (
vite).Now last, we will open a browser window and navigate to the URL used by the launch-editor package to trigger the NTLM authentication. Or we can use
curlto achieve the same.Note the IP address in the HTTP request, and make sure it connects to the IP address of the SMB server. Now we can look at the logs of
smbserver.pyand see the NTLMv2 hash coming in.Severity

launch-editor:
fs.existsSync()existence check can be bypassed on WindowsCVE-2026-112942 / GHSA-587h-7wmj-h5pm
More information
Details
Summary
launch-editorcheckedfs.existsSync(fileName)before passing a supplied path to an editor command. On Windows, an attacker can bypass this check with a crafted path ending in\\..:line:column. This removes the requirement that the attacker be able to place a file with a malicious filename.Combined with the
%escaping issue described in GHSA-698v-4r3x-3vcv, this bypass can lead to OS command injection when an attacker controls the file argument.Impact
Only apps that runs on Windows is affected.
Details
The earlier advisory assumed that
fs.existsSync()required an attacker-controlled filename to exist. This advisory covers a bypass of that requirement.A crafted value ending in
\\..:1:1is interpreted differently bylaunch-editor-middleware,launch-editor, and Windows:launch-editor-middlewarecallspath.resolve()while the final path component is..:1:1, so it is not treated as a parent-directory component.launch-editortreats:1:1as a line-and-column suffix and removes it, leaving a path ending in\\...fs.existsSync()accepts the resulting path as the existing parent directory even though the attacker-controlled preceding component does not exist.Severity

Vite: Cross origin script execution through Vite custom middleware
CVE-2026-112945 / GHSA-9jrq-w75r-8gcw
More information
Details
Summary
When accessing a malicious site while a dev server using Vite is running, that site was able to load scripts in a page served by the dev server.
Impact
Only apps that match the following conditions are affected:
server.transformIndexHtml: this is normally used forserver.middlewareMode: trueorappType: 'custom'. The internal call forappType: 'spa'andappType: 'mpa'does not match this.Details
Vite's SSR guide for 8.2.1 documents the affected setup. The application embeds Vite in middleware mode, reads trusted HTML, and passes the browser's unchanged request URL to the transform:
For a development server at
http://localhost:5173, an attacker can send this URL:In Vite 8.2.1,

indexHtml.tschecks that filename withfs.existsSync, then preserves thehtmlPathsupplied by the attacker asproxyModuleUrl. The inline module rewrite in the same file writes that value into the generatedsrc:The generated value is a valid URL. Its leading

launchEditor(file)function passes the file name as-is to the editor if the file with that file name exists. If the file name starts with-(also+for Vim), the editor treats them as flags rather than positional arguments. For example, Vim treats arguments starting with+as an Ex command. As a result, an existing relative directory such as:is not treated as a filename when passed to Vim. Vim executes the embedded Ex command.
The following editor has a potentially destructive operation exposed to the CLI arguments:

Vite: Files outside

Summary
The content of files outside
server.fssetting can be returned to the browser if the project imports a file path concatenated with theroot. For example, if the project references<path-to-project-root>/etc/hosts, the content of/etc/hostswas possible to be returned.The content of files outside the
server.fs.allowoption can be returned to the browser when a project imports a file whose root-relative path matches an absolute path on the host. For example, referencing<project-root>/etc/hostscould make Vite return the host's/etc/hostsfile.Impact
Only apps that meet all of the following conditions are affected:
--hostor theserver.hostoption)server.fs.denyDetails
When Vite analyzes an in-root import, it rewrites the resolved module ID to a browser URL such as
/etc/hostname. In affected versions, Vite converts that URL withfsPathFromUrland adds the result tosafeModulePaths. BecausefsPathFromUrlensures a leading slash without resolving the URL against the project root, the project URL/etc/hostnameis recorded as if it were the absolute filesystem path/etc/hostname.For a later request to
/@fs/etc/hostname, the raw-filesystem middleware interprets/etc/hostnameas an absolute path. The access check appliesserver.fs.deny, then accepts paths present insafeModulePathsbefore checkingserver.fs.allow. As a result, the request can return the host file instead of the project file that originally populatedsafeModulePaths.PoC
