How this page is checked

StackPrism asks OSV.dev which advisories affect exactly @angular/core 4.1.3, merges duplicates filed under several ids, and ranks them with CISA’s Known Exploited Vulnerabilities list and FIRST EPSS. Release dates and deprecation come from deps.dev and npm, support dates from endoflife.date. No AI writes this page: every sentence comes from that data, refreshed every few hours.

Last checked against npm, OSV.dev, deps.dev, CISA KEV, FIRST EPSS (didn’t answer) and endoflife.date. Findings from that source may be missing; this page refreshes soon.
