CVE-2026-4610Network attack vector

Subscriber-level stored XSS via unsanitized message content

Published Jun 23, 2026 · Updated Jun 23, 2026

Stored XSS in Metagauss ProfileGrid 5.9.9.2 and earlier allows remote authenticated users to inject scripts through private messages. The pm_send_message_to_author function accepts the pm_author_message parameter without sufficient sanitization, and the message renderer outputs it without adequate escaping. Subscriber-level access and an enabled private-messaging flow are sufficient; the injected script executes when a user views the affected content.
