AnalysisAIv1 – Jun 24, 2026

Authenticated command execution in Appsmith versions prior to 2.1 lets any administrator run arbitrary OS commands inside the application's Docker container. The bundled supervisord exposes an XML-RPC management interface on port 9001, which Appsmith's Caddy reverse proxy publishes externally at /supervisor/* on the public ingress; combined with the supervisord password being readable through GET /api/v1/admin/env, an admin can authenticate to supervisord and abuse twiddler.addProgramToGroup to spawn programs that execute shell commands. There is no public exploit identified at time of analysis, and it is not listed in CISA KEV. Fixed in 2.1.

DescriptionCVE.org

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.

Executive ViewAI

Why It Matters

Appsmith versions prior to 2.1 contain an authenticated command execution flaw allowing administrators to execute arbitrary OS commands within the application's Docker container through an exposed supervisord XML-RPC interface. Organizations running affected versions face risk of administrative compromise enabling lateral movement and unauthorized data exfiltration. Immediate upgrade to version 2.1 is required to close this attack vector.

Recommended Action

Within 24 hours: Identify all Appsmith instances and confirm versions prior to 2.1. Within 7 days: Upgrade to Appsmith 2.1 or later and verify application functionality. Within 30 days: Review administrative audit logs for suspicious command execution or supervisord access patterns since deployment.

Business Impact: High
