How this page is checked
StackPrism asks OSV.dev which advisories affect exactly next 12.2.4, 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.
