Collected exploitation and prediction evidence

CISA KEV is observed exploitation evidence. FIRST EPSS is a dated prediction of exploitation in the next 30 days. Missing scores are unknown. This collector requests predictions only for explicit CVE aliases in the public NuGet archive; Microsoft release views retain their existing prediction scope.

No collected risk observation for these identifiers. This does not establish absence of exploitation or a zero probability.

Published

Affected versions of `debug` are vulnerable to regular expression denial of service when untrusted user input is passed into the `o` formatter. As it takes 50,000 characters to block the event loop for 2 seconds, this issue is a low severity issue. This was later re-introduced in version v3.2.0, and then repatched in versions 3.2.7 and 4.3.1. ## Recommendation Version 2.x.x: Update to version 2.6.9 or later. Version 3.1.x: Update to version 3.1.0 or later. Version 3.2.x: Update to version 3.2.7 or later. Version 4.x.x: Update to version 4.3.1 or later.
