A Polymorphic Typing issue was discovered in FasterXML jackson-databind 2.x
before 2.9.9. When Default Typing is enabled (either globally or for a
specific property) for an externally exposed JSON endpoint, the service has
the mysql-connector-java jar (8.0.14 or earlier) in the classpath, and an
attacker can host a crafted MySQL server reachable by the victim, an
attacker can send a crafted JSON message that allows them to read arbitrary
local files on the server. This occurs because of missing
com.mysql.cj.jdbc.admin.MiniAdmin validation.
