Spring Data REST exposes persistence-layer internals in error responses

MEDIUM | JUNE 09, 2026 | CVE-2026-41730

Description

Spring Data REST serializes the full exception cause chain into HTTP error response bodies, potentially exposing persistence-layer internals to HTTP clients.

Affected applications are those that expose a Spring Data REST repository backed by a relational (JDBC/JPA) store and do not apply additional error-handling configuration or a Spring Security access policy that prevents unauthenticated access to the affected endpoints.
