Spring Data REST JSON Patch write-access filter bypass on nested objects
CVE-2026-41728 is a high-severity integrity flaw in Spring Data REST's JSON Patch handling for the application/json-patch+json media type. When resolving a multi-segment JSON Pointer, the implementation does not apply the write-access filter to intermediate path segments. As a result, Jackson read-only property protections on nested objects, collections, and maps can be bypassed. The issue affects applications whose domain model exposes a container property marked read-only at the Jackson level, while nested element types or inner fields do not have equivalent restrictions. An attacker can craft JSON Patch operations that traverse a protected parent path and modify nested state that should not be writable through the REST interface. Affected versions are Spring Data REST 3.7.0 through 3.7.19, 4.3.0 through 4.3.16, 4.4.0 through 4.4.14, 4.5.0 through 4.5.11, and 5.0.0 through 5.0.5; unsupported versions are also reported as affected.
