Research direction

Start with samples/client/petstore-security-test/scala/build.gradle, samples/client/petstore/java/jersey1/build.gradle, and samples/client/petstore/scala/build.gradle. Inspect how jackson-mapper-asl and jackson-databind enter each dependency graph, then run the relevant Gradle dependency or build checks. Done means the listed vulnerable versions are no longer resolved in these sample projects.
