How this page is checked

StackPrism asks OSV.dev which advisories affect exactly Django 4.2.27, 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 PyPI, support dates from endoflife.date. No AI writes this page: every sentence comes from that data, refreshed every few hours.
