Official description
Padding Oracle vulnerability in Apache Druid extension, druid-pac4j. This could allow an attacker to manipulate a pac4j session cookie.
This issue affects Apache Druid versions 0.18.0 through 30.0.0. Since the druid-pac4j extension is optional and disabled by default, Druid installations not using the druid-pac4j extension are not affected by this vulnerability.
