CVE-2020-5245: Remote Code Execution (RCE) vulnerability in dropwizard-validation

February 24, 2020 (updated July 3, 2025)

A server-side template injection was identified in the self-validating (@SelfValidating) feature of dropwizard-validation enabling attackers to inject arbitrary Java EL expressions, leading to Remote Code Execution (RCE) vulnerability.

If you’re using a self-validating bean (via @SelfValidating), an upgrade to Dropwizard 1.3.19 or 2.0.2 is strongly recommended.
