March 27, 2025 (updated October 31, 2025)

Server-Side Request Forgery (SSRF) vulnerability in Apache Kylin. Through a kylin server, an attacker may forge a request to invoke “/kylin/api/xxx/diag” api on another internal host and possibly get leaked information. There are two preconditions: 1) The attacker has got admin access to a kylin server; 2) Another internal host has the “/kylin/api/xxx/diag” api endpoint open for service.

This issue affects Apache Kylin: from 5.0.0 through 5.0.1.

Users are recommended to upgrade to version 5.0.2, which fixes the issue.
