Associated Vulnerability

Title: Remote Code Execution in Apache Unomi (CVE-2020-13942)
Description:It is possible to inject malicious OGNL or MVEL scripts into the /context.json public endpoint. This was partially fixed in 1.5.1 but a new attack vector was found. In Apache Unomi version 1.5.2 scripts are now completely filtered from the input. It is highly recommended to upgrade to the latest available version of the 1.5.x release to fix this problem.

offers the possibility to call static Java classes from the JDK
that could execute code with the permission level of the running Java process.
