Information

The following conditions are needed for an exploit, we recommend avoiding all if possible: * Deserialization from sources you do not control * `enableDefaultTyping()` * `@JsonTypeInfo using `id.CLASS` or `id.MINIMAL_CLASS` * avoid org.apache.commons.dbcp2.datasources.PerUserPoolDataSource and org.apache.commons.dbcp2.datasources.SharedPoolDataSource in the classpath
