The \u003ccode\u003e/run_live\u003c/code\u003e WebSocket endpoint accepts connections from any origin by default (hardcoded via \u003ccode\u003esetAllowedOrigins(\"*\")\u003c/code\u003e in versions 0.1.0 through 1.5.0, and defaulting to \u003ccode\u003e*\u003c/code\u003e via \u003ccode\u003eadk.web.cors.origins\u003c/code\u003e in versions 1.6.0 through 1.12.0), and since version 0.4.0 the REST API returns \u003ccode\u003eAccess-Control-Allow-Origin: *\u003c/code\u003e by default. Because the server has no authentication and requests originate from the developer\u0027s browser (so binding to localhost does not prevent exploitation), a cross-origin page can send messages to the agent (triggering registered tools), stream agent responses, and list, read, create, or delete sessions and artifacts. In versions 1.6.0 through 1.12.0, users can mitigate the issue by setting the \u003ccode\u003eadk.web.cors.origins\u003c/code\u003e property to an explicit allowlist of trusted origins (such as \u003ccode\u003ehttp://localhost:8000\u003c/code\u003e). The vulnerability is fixed in version 1.13.0, which enforces a same-origin default for CORS and the \u003ccode\u003e/run_live\u003c/code\u003e WebSocket endpoint, and rejects DNS-rebinding requests over loopback.\u003c/p\u003e"
