Expression language injection through JaninoEventEvaluator in a
configuration file. Fixed on the 1.3 line in 1.3.15 (GHSA lists logback-core
< 1.3.15) by commit c17e58838, which deletes JaninoEventEvaluator and
logback-core's ch.qos.logback.core.boolex.JaninoEventEvaluatorBase. Neither
class exists in the 1.3.15 tag (`git ls-tree -r v_1.3.15 | grep JaninoEventEvaluator`
is empty). trivy matches only the 1.5.13 fixed version.
