Cross-user data disclosure via cached Uni context
Published Dec 6, 2023 · Updated Aug 4, 2026
Information exposure in Red Hat build of Quarkus allows remote authenticated users to receive another user's cached POST response. CacheResultInterceptor returns a cached Uni on its original completion context instead of emitting the item on the request's captured context. Exploitation requires low privileges and an endpoint that caches a Uni with @CacheResult; impact is limited to response-data disclosure.
