The flaw resides within the \u003ccode\u003ereceiver_thread\u003c/code\u003e function in the \u003ccode\u003ehttp_request\u003c/code\u003e component of \u003ccode\u003eclaw/services/swarm/swarm.c\u003c/code\u003e. This vulnerability allows a remote unauthenticated attacker to manipulate HTTP requests, compelling the vulnerable \u003ccode\u003ert-claw\u003c/code\u003e application to make arbitrary requests to internal or external systems from the server's perspective. An exploit for CVE-2026-16128 has been publicly released, increasing the risk of widespread attacks.
