CVE-2026-50189Public exploitNetwork attack vector

Administrator RCE via exposed Supervisord XML-RPC

Published Jun 24, 2026 · Updated Jun 24, 2026

Remote code execution in Appsmith before 2.1 allows remote authenticated users with administrator access to run container commands. An exposed /supervisor/RPC2 Caddy route accepts Supervisord XML-RPC calls, while the admin environment API reveals the required password. The twiddler.addProgramToGroup method registers attacker-supplied commands for immediate execution as the appsmith user inside the Docker container.
