CVE-2023-6158Network attack vector

Unauthenticated post metadata modification via unchecked AJAX

Published Jan 10, 2024 · Updated Apr 8, 2026

Missing authorization in EventON Pro 4.5.4 and earlier and EventON Lite 2.2.7 and earlier allows remote attackers to alter post metadata. The evo_eventpost_update_meta AJAX handler accepts unauthenticated requests and updates or deletes attacker-selected post metadata without a capability check. No account is required; exploitation can change or remove event data and inject content through supported metadata parameters.
