Code Execution in Activepieces Workflow Automation

Publication date: 2026-08-11

Last updated on: 2026-08-12

Assigner: GitHub, Inc.

Description

Activepieces is an open source AI workflow automation platform. Prior to 0.80.0, the worker's code-compilation pipeline builds the on-disk path for a Code step from the step's name and passes that path to a shell-invoked build command. A step name containing shell metacharacters can break out of the intended build invocation and execute arbitrary commands during compilation before any code sandbox is created. An authenticated user with permission to create or edit a flow can execute commands as the worker process user, read and write the worker filesystem, exfiltrate environment secrets, and reach internal services available to the worker. This issue is fixed in version 0.80.0.

CWE ID	Description
CWE-78	The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component.

Attack-Flow Graph

Executive Summary

This is a Remote Code Execution (RCE) vulnerability in Activepieces, an AI workflow automation platform. It affects versions before 0.80.0. The issue occurs in the worker's code-compilation pipeline where a step name containing shell metacharacters can break out of the intended build command and execute arbitrary commands before any sandboxing is applied.

Detection Guidance

Detecting this vulnerability requires checking if your Activepieces instance is running a vulnerable version (0.79.4 or earlier). Inspect the version of Activepieces installed on your system or accessible via API endpoints. Look for unusual command execution patterns in system logs, especially during flow compilation or worker processes. Monitor network traffic for unexpected outbound connections from the worker process.

Impact Analysis

An authenticated user with permission to create or edit a flow can exploit this to execute commands as the worker process user, read and write files on the worker filesystem, steal environment secrets, and access internal services. In multi-tenant setups, this could expose data from all tenants.

Compliance Impact

This vulnerability could lead to unauthorized access to sensitive data, violating GDPR and HIPAA compliance requirements for data protection and confidentiality. Exploitation may result in data breaches, unauthorized disclosure, or loss of data integrity.

Mitigation Strategies

Immediately upgrade Activepieces to version 0.80.0 or later to patch the vulnerability. If upgrading is not immediately possible, restrict permissions for flow creation and editing to trusted users only. Run the worker process as a non-root user to limit potential damage from exploitation. Disable shell invocation for build commands if supported by your configuration.
