## Overview

In FasterXML jackson-databind before versions 2.13.4.1 and 2.12.17.1, resource exhaustion can occur because of a lack of a check in primitive value deserializers to avoid deep wrapper array nesting, when the UNWRAP_SINGLE_VALUE_ARRAYS feature is enabled.

## Affected

- `jackson-databind < 2.12.7.1`
- `jackson-databind >= 2.13.0, < 2.13.4.1`
- `quarkus < 2.13.3`
- `debian_linux = 10.0`
- `debian_linux = 11.0`
- `oncommand_workflow_automation`

## Remediation

Upgrade past the affected range:

- `jackson-databind 2.13.4.1`
- `quarkus 2.13.3`
