CVE-2026-50189: CWE-183: Permissive List of Allowed Inputs in appsmithorg appsmith
Appsmith versions prior to 2.1 include a vulnerability where the bundled supervisord exposes an XML-RPC interface on port 9001, accessible externally via a reverse proxy. An authenticated administrator can retrieve the supervisor password through an API endpoint and then execute arbitrary OS commands inside the Docker container. This issue is addressed in version 2.1.
AI Analysis
Technical Summary
Appsmith before version 2.1 exposes its supervisord XML-RPC interface on port 9001 through a public ingress reverse proxy route. The APPSMITH_SUPERVISOR_PASSWORD can be obtained by authenticated administrators via a GET request to /api/v1/admin/env. Using this password, an attacker with administrator privileges can send arbitrary XML-RPC commands to supervisord, including twiddler.addProgramToGroup, enabling execution of OS commands within the Docker container. This vulnerability is fixed in Appsmith 2.1.
Potential Impact
An authenticated administrator can execute arbitrary operating system commands inside the Docker container hosting Appsmith by exploiting the exposed supervisord XML-RPC interface and the disclosed 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.
