Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis No additional public attack-surface or AI-review details are available. ## Affected versions and remediation This report applies to @vite-tab/tab@5.7.0. The same advisory and Firewall decision cover these 2 recorded versions: 3.15.10, 5.7.0. - Avoid installing @vite-tab/tab@5.7.0. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1. High: Osv Malicious Advisory - **Category:** External Intel - **Confidence:** 100.0% \`@vite-tab/tab\` republishes Vite's codebase under a different name while impersonating the upstream project: \`package.json\` declares \`bin: { vite: 'bin/vite.js' }\` (hijacking the \`vite\` command on $PATH), \`author: 'Evan You'\`, \`repository: git+https://github.com/vitejs/vite.git\`, and \`homepage: https://vitejs.dev\`. Appended to \`bin/vite.js\` after the legitimate Vite bootstrap is a self-decoding string table (\`var \_$\_4445=(function(k,p){...})("...",4606094)\`) built via a Fisher-Yates-style scramble with \`\\x25\`/\`\\x23\` substitution markers; all sensitive identifiers (\`https\`, \`get\`, \`request\`, \`JSON.parse\`, \`child\_process\`, \`spawn\`, \`eval\`, host fragments) are referenced as indices into this table to defeat static review. At runtime the decoded routines perform an HTTPS GET followed by a JSON-RPC POST (\`{jsonrpc, method, params, id:1}\`) to a dynamically resolved hostname, base64-decode and XOR-decrypt the response, and pass it to \`eval(r)\`; a second fetched payload is launched via \`child\_process.spawn(..., {detached:true, windowsHide:true})\`, with a 30-second throttle. The fetch loop runs every time a developer invokes the hijacked \`vite\` command, giving the publisher arbitrary remote code execution on the developer machine with persistence via detached child processes. The remote-hostname JSON-RPC lookup makes the C2 endpoint resistant to static domain blocking. ## Dependencies and install lifecycle - **Lifecycle scripts present:** Yes - **Published lifecycle scripts:** prepublishOnly - **Dependencies:** 3 - **Optional dependencies:** 1 - **Peer dependencies:** 8 - **Development dependencies:** 63 - **Published dependency-graph edges:** 12 ### Published dependency entries - esbuild ^0.21.3 (Dependency) - postcss ^8.4.41 (Dependency) - rollup ^4.13.0 (Dependency) - fsevents ~2.3.3 (OptionalDependency) - @types/node ^18.0.0 || \>=20.0.0 (PeerDependency) - less \* (PeerDependency) - lightningcss ^1.21.0 (PeerDependency) - sass \* (PeerDependency) - sass-embedded \* (PeerDependency) - stylus \* (PeerDependency) - sugarss \* (PeerDependency) - terser ^5.4.0 (PeerDependency) ## Package metadata - **Package:** @vite-tab/tab - **Ecosystem:** npm - **Version:** 5.7.0 - **License:** MIT - **Version published:** 2026-07-07T17:55:32.573Z - **Package first seen:** 2026-07-08T17:25:10.588Z - **Package last seen:** 2026-09-22T02:28:08.565Z - **Known versions:** 3 - **Latest version:** 0.0.1-security - **Appeal under review:** No - **Description:** Native-ESM powered web dev build tool - **Author:** Evan You - **Maintainers:** vite-tab - **Keywords:** frontend, framework, hmr, dev-server, build-tool, vite - **Runtime engines:** node: ^18.0.0 || \>=20.0.0 - **Artifact files:** 31 - **Artifact unpacked size:** 3,264,836 bytes - **Artifact signatures:** 1 - **Attestations:** No ## References - [HTML security report]() - [Repository]() - [Homepage]() - [Issues]() - [OpenSSF/OSV advisory]() - [PACKAGE]() - [PACKAGE]()
