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 (0174148efc99cd1130b3b9f2c57599aac0f80ead454fd7dc0f397386db891b0c) The package ships console.js, which when loaded in a browser on any host matching duel.com fetches https://unpkg.com/[email protected]/1.js and https://unpkg.com/[email protected]/ui.js and executes both via (0, eval)(...). On other hosts it redirects the page to duel.com. The declared main/unpkg entry 1.js is a ~740KB single-line Function("ZU7mhwD", "...") loader built from hex-escaped char arrays and a rotor-style decoder, with no readable source. Package metadata is placeholder-quality (name xa424234657567, no README, no repository), inconsistent with a library and consistent with a payload-delivery artifact. Consuming this package on a page served under duel.com results in remote, mutable, attacker-controlled code executing in the page context.
