CVE-2026-50189: CWE-183: Permissive List of Allowed Inputs in appsmithorg appsmith
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.
AI Analysis
Technical Summary
The vulnerability in Appsmith before version 2.1 involves the exposure of the supervisord XML-RPC interface on port 9001, reachable externally through a reverse proxy. The APPSMITH_SUPERVISOR_PASSWORD can be obtained by authenticated administrators via an API endpoint, enabling them to send arbitrary XML-RPC commands to supervisord. This allows execution of OS commands inside the Docker container using the twiddler.addProgramToGroup method. The vulnerability is fixed in Appsmith 2.1.
Potential Impact
An authenticated administrator can execute arbitrary operating system commands inside the Docker container running Appsmith by exploiting the exposed supervisord XML-RPC interface and the exposed supervisor password. This could lead to full container compromise and potentially impact the host environment depending on container isolation.
Mitigation Recommendations
Upgrade Appsmith to version 2.1 or later, where this vulnerability is fixed. No official patch or temporary fix is indicated other than upgrading. Until upgraded, restrict access to the supervisord interface and the API endpoint exposing the supervisor password to trusted users only.
