CISA ADP Vulnrichment

Why this deserves its current priority

CVSS is 4.6. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

Affected scope and exposure questions

The current feed maps n/a/n/a (generic). Check affected ranges and fixed versions before updating.

Recommended response

1. 1Check inventory. Check lockfiles and deployed manifests for n/a/n/a.
2. 2Review the reported fix. Monitor this advisory for an available fix and review any installs of the affected package.
