CVE-2024-43919Public exploitNetwork attack vector

Unauthorized display-type changes via missing capability check

Published Nov 1, 2024 · Updated Apr 28, 2026

Missing authorization in YARPP 5.30.10 and earlier allows remote attackers to change display types through a crafted HTTP request. The directly reachable includes/yarpp_pro_set_display_types.php script accepts attacker-controlled types[] values after ypsdt=false bypasses its initial check, without a capability check. No authentication or user interaction is required; the demonstrated consequence is limited to changing the plugin's display-type configuration.
