What is CVE-2026-4610?

The ProfileGrid plugin for WordPress contains a vulnerability that allows authenticated users with Subscriber-level access or higher to exploit the 'pm_author_message' parameter in the pm_send_message_to_author function. This flaw arises from inadequate input sanitization and output encoding, enabling attackers to inject malicious scripts. When users access affected pages, these scripts may execute, compromising user data and session integrity. Although a partial fix was introduced in version 5.9.8.5, earlier versions remain vulnerable, highlighting the importance of timely updates and secure coding practices.

Affected Version(s)

ProfileGrid – User Profiles, Groups and Communities 0 <= 5.9.9.2
