Short explanation
Events Manager WordPress plugin before 7.4.1 allows unauthenticated users to escalate to administrator privileges via improper capability mapping. This enables password changes, account deletion, and privilege escalation without authentication. No official patch status is confirmed in public sources.
This vulnerability enables full administrative access without authentication, posing a severe risk to WordPress installations. Attackers can gain full control over user accounts and system settings. Immediate remediation is required to prevent compromise.
What should be done?
- Upgrade to Events Manager version 7.4.1 or later
- Apply vendor-recommended patch if available
- Verify patch status through official vendor advisories
Chain of evidence and sources

Açık, plugin'da yetki eşleme hatası nedeniyle ortaya çıkar ve WordPress'in ilgili olmayan eylemler için yapmış olduğu erişim kontrol kararlarını atlar.
Kimlik doğrulama olmadan bir kullanıcı, bir hesabın kullanıcı kimliği, Events Manager bir gönderi kimliğiyle eşleşiyorsa, şifre değiştirme, yönetici olma veya hesap silme yapabilir.
Show the technical text from the sources
The Events Manager WordPress plugin before 7.4.1 does not properly scope its capability mapping, discarding the access control decisions WordPress already made for unrelated privileged actions, which allows unauthenticated users to change the password of, escalate to Administrator, or delete any account whose user ID happens to match the ID of one of the Events Manager WordPress plugin before 7.4.1's own posts.
