## Technical details

A Server-Side Request Forgery (SSRF) vulnerability exists in the swarm RPC service of zevorn rt-claw up to version 0.2.0. The 'receiver_thread' function in 'claw/services/swarm/swarm.c' dispatches unauthenticated UDP RPC packets to 'handle_rpc_request', which invokes the 'http_request' tool with attacker-controlled JSON parameters. On Linux builds, the 'url' parameter is passed directly to libcurl via 'claw_net_get' without validation of the destination address. A remote attacker can exploit this to coerce the application into fetching resources from loopback (127.0.0.1) or internal network endpoints and returning the response body in the RPC reply. As of the advisory date, the project has not responded to the issue report.
