CVE-2025-1247Network attack vector

Cross-request data exposure via shared endpoint instances

Published Feb 13, 2025 · Updated Aug 4, 2026

Data exposure in Quarkus REST before 3.18.2 allows remote authenticated users to receive another request's parameters during concurrency. Unscoped REST resource classes reuse an endpoint instance, so field-injected headers and other request parameters retain values across requests. Exploitation requires concurrent access to an affected endpoint that uses field injection without request scope, enabling data access, request manipulation, or user impersonation.
