CVE-2026-12073

ProfileGrid plugin has an authorization bypass through user-controlled key vulnerability, allowing exploitation of incorrectly configured access control levels. Affects versions up to 6.0.0.2.

The 'ProfileGrid' WordPress plugin before version 6.0.0.0 does not perform authorization checks when listing a group's pending membership requests, allowing any authenticated user such as a Subscriber to disclose the names and request dates of the users awaiting approval to join any group, including private ones.

The ProfileGrid WordPress plugin before version 5.9.9.8 does not verify that a notification belongs to the requesting user before deleting it. Any authenticated user (e.g., Subscriber) can delete other users' notifications by enumerating notification identifiers.

The ProfileGrid WordPress plugin before 5.9.9.8 does not restrict which group an anonymous visitor may register into through its front-end registration. Unauthenticated users can register directly into a privileged group and be granted that group's configured role, up to Administrator, leading to privilege escalation.

The ProfileGrid WordPress plugin before version 5.9.9.7 does not perform a capability check on its license management actions, relying only on a nonce that is exposed to any logged-in user, allowing authenticated users with Subscriber-level access and above to overwrite the site's premium license settings.

The ProfileGrid WordPress plugin before version 5.9.9.7 does not perform any authorization or ownership check on some of its private-message thread actions, allowing authenticated users with Subscriber-level access and above to soft-delete, tamper with the metadata of, and mark as read other users' private message threads.

The ProfileGrid WordPress plugin before version 5.9.9.7 does not verify PayPal IPN notifications before granting paid group membership, allowing unauthenticated attackers to forge a payment notification and mark any user as a paid member of any group without any payment.

The ProfileGrid plugin for WordPress contains an authentication bypass vulnerability via an alternate path or channel, allowing password recovery exploitation. This affects versions up to and including 5.9.9.6.

Cross-Site Request Forgery (CSRF) vulnerability in ProfileGrid by Metagauss (profilegrid-user-profiles-groups-and-communities) allows an attacker to perform unauthorized actions on behalf of an authenticated user. The issue affects versions from n/a through 6.0.0.2.

The ProfileGrid plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'pm_author_message' parameter in the pm_send_message_to_author function in all versions up to 5.9.9.2 due to insufficient input sanitization and output escaping.
