NewCVE-2026-47849 (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 Authorization Bypass Through User-Controlled Key via the PATCH process. An attacker can overwrite identifier and version properties by sending crafted RFC 6902 JSON Patch requests, potentially bypassing optimistic-locking protections and causing unauthorized modification or replacement of records belonging to other users. This is only exploitable if the entity type declares an identifier or version property that is visible to Jackson's deserialization model (i.e., the property has a public setter and is not explicitly excluded via @JsonIgnore).
