CVE-2026-50189

Appsmith is a platform to build admin panels, internal tools, and dashboards. Prior to 2.1, Appsmith's bundled supervisord exposes an XML-RPC interface on port 9001, reachable from outside the container via a Caddy reverse-proxy route at /supervisor/* on the public ingress. Combined with the APPSMITH_SUPERVISOR_PASSWORD exposed via GET /api/v1/admin/env, any authenticated administrator can send arbitrary XML-RPC calls to supervisord and execute OS commands inside the Docker container via twiddler.addProgramToGroup. This vulnerability is fixed in 2.1.

Summary		(es) Appsmith es una plataforma para construir paneles de administración, herramientas internas y cuadros de mando. Antes de 2.1, el supervisord incluido de Appsmith expone una interfaz XML-RPC en el puerto 9001, accesible desde fuera del contenedor a través de una ruta de proxy inverso de Caddy en /supervisor/* en el ingreso público. Combinado con la APPSMITH_SUPERVISOR_PASSWORD expuesta a través de GET /api/v1/admin/env, cualquier administrador autenticado puede enviar llamadas XML-RPC arbitrarias a supervisord y ejecutar comandos del sistema operativo dentro del contenedor Docker a través de twiddler.addProgramToGroup. Esta vulnerabilidad está corregida en 2.1.
