In FasterXML jackson-databind before 2.12.7.1 and in 2.13.x before 2.13.4, resource exhaustion can occur because of a lack of a check in BeanDeserializer._deserializeFromArray to prevent use of deeply nested arrays. This issue can only happen when the UNWRAP_SINGLE_VALUE_ARRAYS feature is explicitly enabled.
