CVE-2025-43797Network attack vector

Unauthorized site access via open membership default

Published Sep 15, 2025 · Updated Sep 15, 2025

Insecure default site membership in affected Liferay Portal and DXP releases allows remote authenticated users to join newly created sites. The site-creation path initializes the membership type as Open instead of requiring an administrator to select an access-restricting type. Any registered account can consequently obtain site membership and exercise whatever read or write permissions the site grants to ordinary members.
