CVE-2026-47849Network attack vector

Authenticated record overwrite via unguarded JSON Patch

Published Aug 27, 2026 · Updated Aug 27, 2026

Improper object-attribute control in Spring Data REST affected releases allows remote authenticated users to overwrite protected entity fields. The RFC 6902 JSON Patch path omits the identifier and version-property guard used by PUT and merge patch, then binds attacker-controlled values. Reachability requires authenticated PATCH access and a Jackson-visible @Id or @Version property; writes can bypass optimistic locking or overwrite another principal's record.
