NewCVE-2026-47850 (opens in a new tab)How to fix?
Upgrade org.springframework.data:spring-data-rest-core to version 5.0.7, 5.1.1 or higher.
Overview
org.springframework.data:spring-data-rest-core is a Spring Data REST.
Affected versions of this package are vulnerable to Improper Enforcement of Behavioral Workflow via the handling of HTTP PUT requests against immutable aggregate types. An attacker can bypass optimistic-locking protections by submitting a crafted request body that includes a manipulated version property, resulting in stale writes being silently accepted and concurrent updates being overwritten.
Note: This is only exploitable if the aggregate root is immutable or allows a body-driven polymorphic subtype change, and the version property is visible to Jackson's deserialization model and not excluded via @JsonIgnore.
