id: CVE-2024-43919

info:
  name: YARPP <= 5.30.10 - Missing Authorization
  author: s4e-io
  severity: critical
  description: |
    The YARPP Yet Another Related Posts Plugin plugin for WordPress is vulnerable to unauthorized access due to a missing capability check in the ~/includes/yarpp_pro_set_display_types.php file in all versions up to, and including, 5.30.10. This makes it possible for unauthenticated attackers to set display types.
