POST /v1/tools/cve-lookup

unprobed

Look up a CVE by id, or search the NVD catalogue by keyword. Returns the CVSS base score and vector with its version (v4, v3.1, v3.0 or v2 - whichever NVD published), severity, CWE classification, publication and last-modified dates, vulnerability status and references. Straight from the NIST National Vulnerability Database.

Verdict: not verified by an unpaid GET. not probed yet. This says nothing about whether the route works when called as declared.
