In order for this to happen, the application must dynamically create multiple clients (such as HttpClient or TcpClient ) that rely on different custom configuration. This can lead to traffic being routed to unintended destinations.","severity":null,"techs":["spring","java"],"cves":["CVE-2026-47843"],"tags":["security"],"source":{"id":"spring-security","name":"Spring Security Advisories"},"published_at":"2026-08-20T00:00:00.000Z","fetched_at":"2026-10-21T16:17:45.704Z"}
