Overview

org.apache.velocity:velocity-engine-core is a template engine written in Java.

Affected versions of this package are vulnerable to Arbitrary Code Execution. An attacker that is able to modify Velocity templates may execute arbitrary Java code or run arbitrary system commands with the same privileges as the account running the Servlet container. This applies to applications that allow untrusted users to upload/modify velocity templates running Apache Velocity Engine.

Note Users of org.apache.velocity:velocity should update to org.apache.velocity:velocity-engine-core version 2.3 to mitigate this vulnerability.
