CVE-2020-13942

9.8 criticalEPSS 68%

Critical (9.8) in apache unomi. EPSS 68% chance of exploitation in the next 30 days. Fixed in org.apache.unomi:unomi 1.5.2.

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.
