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 (86c68c82f6ead4ab3b823b81fd6805991bfdd65cdc901d83aeb561cdd8f27b19) package.json declares `"libsignal": "github:tenka-san/libsignal-node"` — an off-registry dependency source pointing at a personal-user GitHub repository with no commit SHA, no tag, and no integrity check. On `npm install`, npm clones the current tip of that repository and installs whatever it contains, running any lifecycle scripts (`preinstall`/`install`/`postinstall`/`prepare`) inside the fetched tree on the installer's machine. The dependency key `libsignal` shadows the well-known Signal protocol library, but the source is a personal user's fork rather than the upstream signalapp organization, so whoever controls the tenka-san/libsignal-node repository controls install-time code execution on every installer of this package. The source is mutable — content that resolves benign today can be replaced without any change to this package. A secondary observation: lib/Utils/generics.js line 403 references `ping`, but this is unrelated to the primary install-time execution concern.
