CVE-2024-45384

Summary

Padding Oracle vulnerability in Apache Druid extension, druid-pac4j. This could allow an attacker to manipulate a "pac4j" session cookie. This issue affects org.apache.druid:druid-processing 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. While we are not aware of a way to meaningfully exploit this flaw, we nevertheless recommend upgrading to the fixed version which fixes the issue and ensures you have a strong druid.auth.pac4j.cookiePassphrase as a precaution.
