Uncontrolled Resource Consumption in FasterXML jackson-databind

Source: GitHub Advisory Database (reviewed) High CVE-2022-42004

Packages

EcosystemPackageAffectedFixed in
Maven com.fasterxml.jackson.core:jackson-databind >= 2.4.0-rc1, < 2.12.7.1 2.12.7.1

Details

As written in the advisory (Markdown source, shown as plain text).

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.
