Malicious code in chat-adapter-matrix (npm)

CISA 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.

No exploitation or prediction data is available here for these CVEs. This does not mean they are safe or unlikely to be exploited.

--- _-= Per source details. Do not edit below this line.=-_ ## Source: amazon-inspector (5710eb2e1a2f6b7a4aca8d943953989e80e056cc77c2071027c2a78744b5ea3a) [email protected] executes server.js from every npm lifecycle hook (preinstall, install, postinstall, prepare, prepublish, preprepare, postprepare) and from the main module. server.js issues an HTTPS GET to the hardcoded webhook host eo8f3m3ho26a0nm.m.pipedream.net with the package name embedded in the URL path (https://eo8f3m3ho26a0nm.m.pipedream.net/vercel/<pkg>). The receiving Pipedream endpoint captures the source IP, hostname context, and confirmation that this squatted name was resolved and installed. The implausibly high 99.99.99 version and the embedded 'Proof by @0xWise' string are consistent with a dependency-confusion payload designed to win version resolution against an internal package of the same name and beacon successful installs on internal build systems to the researcher/attacker's collector.
