CVE-2021-26919 is a high-severity vulnerability affecting Apache Druid, where trusted users with specific permissions can leverage the MySQL JDBC driver to execute arbitrary code on Druid server processes. This is possible if the driver's properties are not properly mitigated, allowing a malicious MySQL server to compromise the Druid instance. The vulnerability carries a CVSS score of 8.8, indicating a high potential for complete compromise of confidentiality, integrity, and availability. While no active exploitation or public exploit code has been identified, and community discussion is minimal, its high EPSS and FAUCET Risk scores suggest a significant threat that should be addressed by upgrading to Apache Druid 0.20.2 or later.
