CVE-2022-29442Network attack vector

Stored script execution via unsanitized private-message content

Published Jun 15, 2022 · Updated Apr 28, 2026

Stored XSS in Rilwis Private Messages For WordPress 2.1.10 and earlier allows remote authenticated users to execute script via private messages. The rwpm_send path passes posted content through stripslashes and esc_sql but performs no HTML sanitization before inserting it into the message table. Subscriber access is sufficient to plant the payload, and execution requires another user to view the stored message.
