Summary
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.
