How this catalog works

Active means a non-withdrawn CVE List record with a validated alias, English description, publication date, and source reference. Published is the CVE Program date; First seen at HOL is when this feed first indexed the record; Modified and Source checked describe later feed activity. Severity uses the reported source value when present, otherwise a valid CVSS score supplies the displayed band. Unmapped records do not imply package coverage.

Put Guard beside your supply-chain workflow.

How this catalog works

Active means a non-withdrawn CVE List record with a validated alias, English description, publication date, and source reference. Published is the CVE Program date; First seen at HOL is when this feed first indexed the record; Modified and Source checked describe later feed activity. Severity uses the reported source value when present, otherwise a valid CVSS score supplies the displayed band. Unmapped records do not imply package coverage.

Put Guard beside your supply-chain workflow.
