Malicious code in @prime0/pcomatch (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 (08299e41eb4feb9e324854bf5cd3386e6e52696b4b11443254374897a1ad3816) index.js and the postinstall lifecycle script contact a hardcoded bare-IP endpoint at http://69.48.229.140:8080 over plain HTTP. On `npm install`, the postinstall hook collects host identifiers (hostname, username, platform, arch, cwd, node version, pid, all non-internal IP addresses, uptime, package name) and POSTs them as JSON to /b. On `require()` of the package main, the module beacons the same host, then polls /c every 30 seconds for JSON commands and executes the `c` field via child_process.exec, POSTing stdout/stderr back to /r. A source comment self-identifies the module as a stealth typosquat agent, while package.json advertises only a generic "small utility" description.
