Although the attack vector is limited to authenticated users, the potential for data loss or alteration makes it a concern for sites with active event management workflows."}}}}, "created": "2026-02-26T13:10:54.927358+00:00", "updated": "2026-04-15T18:15:10.814813+00:00", "vendors": ["stellarwp", "stellarwp$PRODUCT$the_events_calendar", "wordpress", "wordpress$PRODUCT$wordpress"]}
