CVE-2026-47850Network attack vector

Authenticated concurrent-update overwrite via client-controlled version property

Published Aug 26, 2026 · Updated Aug 27, 2026

Improper attribute control in Spring Data REST allows remote authenticated users to overwrite concurrent updates through HTTP PUT requests. For immutable aggregate roots, the PUT merge path returns the request-body object and restores ignored stored fields but not the persisted @Version property, so a client-supplied version is saved. Exposure requires PUT access, a Jackson-visible version field, and reliance on optimistic locking without mandatory If-Match or ETag preconditions.
