Trivy's own label is CRITICAL. Rated critical by NVD, GHSA.
Description
Netflix Titus uses Java Bean Validation (JSR 380) custom constraint validators.

If an attacker can inject arbitrary data in the error message template being passed to ConstraintValidatorContext.buildConstraintViolationWithTemplate() argument, they will be able to run arbitrary Java code.
