Malicious code in concierge-sdk (npm)
Exploitation and risk
Source statusCISA KEV lists vulnerabilities known to be exploited. FIRST EPSS estimates the likelihood of exploitation in the next 30 days. An unavailable score does not mean zero risk.
Which CVEs have scores here?
This view includes predictions for CVE identifiers explicitly listed in public NuGet advisories. Microsoft release pages have their own prediction coverage. Check source status for the scope and latest checks.
No exploitation or prediction data is available here for these CVEs. This does not mean they are safe or unlikely to be exploited.

Published--- _-= Per source details. Do not edit below this line.=-_ ## Source: amazon-inspector (4de458111994244a0a590117185f9e345ff27043c129d4ea24fcb3be5f98f67b) The package's declared postinstall script executes exfil_v2.js at `npm install` time. That script harvests the full process environment, current working directory, and config/secret files (.env, secrets.json, /etc/environment, /etc/profile, workflow files, git-history secret matches), curls the Azure Instance Metadata Service at 169.254.169.254 to obtain a managed-identity access token for vault.azure.net and lists Key Vault secrets with it, and uses the runner's GITHUB_TOKEN against api.github.com to read repository secrets and Actions artifacts. All collected data is POSTed to a hardcoded webhook.site endpoint. A sibling exfil.js duplicates full process.env exfiltration to the same webhook.site collector under User-Agent `continental-sdk/1.0`.
