CVE-2026-35216 Details
Description
Budibase is an open-source low-code platform. Prior to version 3.33.4, an unauthenticated attacker can achieve Remote Code Execution (RCE) on the Budibase server by triggering an automation that contains a Bash step via the public webhook endpoint. No authentication is required to trigger the exploit. The process executes as root inside the container. This issue has been patched in version 3.33.4.
A remote code execution vulnerability has been identified in Budibase, an open-source low-code platform, prior to version 3.33.4. The issue allows an unauthenticated attacker to execute arbitrary commands on the Budibase server as the root user within the application container. This exploitation is achieved by triggering an automation that includes a Bash step, using the public webhook endpoint which lacks authentication. The vulnerability arises because the Bash step can process template variables from the webhook payload, enabling the injection of malicious commands that are executed with elevated privileges.
Users can update to Budibase version 3.33.4 or later, where this vulnerability has been patched.
