CVE-2026-55425
Description
Graylog is a free and open log management platform. From 7.1.0 until 7.1.4 and 7.2.0-alpha.2, the System Catalog entity titles endpoint in graylog2-server/src/main/java/org/graylog2/rest/resources/system/contentpacks/titles/EntityTitleServiceImpl.java allows an authenticated user to request composite display fields without verifying that every selected field is readable. A user can retrieve protected values, including the password hash on a readable user record; ordinary users are limited to their own permitted records, while administrators can retrieve hashes for all users. This issue is fixed in versions 7.1.4 and 7.2.0-alpha.2.
