Upgrade com.fasterxml.jackson.core:jackson-databind to version 2.18.8, 2.21.4 or higher.
Overview
com.fasterxml.jackson.core:jackson-databind is a library which contains the general-purpose data-binding functionality and tree-model for Jackson Data Processor.
Affected versions of this package are vulnerable to Server-side Request Forgery (SSRF) in the JDKFromStringDeserializer class, which constructs InetSocketAddress and resolves the hostname through DNS at deserialization time. An attacker can force the server to issue outbound DNS lookups for chosen hostnames by submitting JSON that is deserialized into a type holding an InetSocketAddress field, with no authentication required. The observable effect is limited to DNS resolution of attacker-chosen names, useful for out-of-band interaction or internal resolver probing rather than a full outbound request, and it applies only where the application deserializes untrusted JSON into types containing such fields.
