CVE-2026-4609
HighSummary
The ProfileGrid – User Profiles, Groups and Communities plugin for WordPress is vulnerable to unauthorized access due to a missing capability check on the pm_invite_user function in all versions up to and including 5.9.8.4. This allows authenticated attackers, with Subscriber-level access and above, to add themselves or any registered user to any ProfileGrid group, including closed and paid groups, bypassing all authorization and payment gates.
Risk Assessment
The organization is at risk of unauthorized access to closed groups and user data, which may lead to information leaks and privacy violations. Attackers could exploit this vulnerability to manipulate user groups.
Recommendation
It is recommended to update the ProfileGrid plugin to the latest version to eliminate this vulnerability. Additionally, conducting an audit of user permissions in the system is advisable.
